Mararn – New Zealand’s only production McLaren

15 August, 2025

Even being saddled with a name like Mararn does not spoil the raw appeal of this local kit version of McLaren’s original but ill-fated road-going supercar
By Patrick Harlow

I met Andrew Farrow in the little South Island town of Rangiora, where he introduced me to the then current version of his constantly changing car collection. He owns the Eyrewell Forest Motor Company. Not having a forecourt, his sales generally occur online where he buys and sells cars to add to his fluid collection. An example of what I mean by fluid is the F-Type Jaguar which he purchased recently and enjoys driving. It is advertised on his website and will eventually sell, at which point it will be replaced by another exotic he would like to own such as a Ferrari 599. Consequently, his collection is always in a state of flux, and he never has time to get bored with a particular car as another car will always be somewhere on the horizon. 
I had gone to see one of the more permanent cars in his collection and one of his favourites, a McLaren M6GT replica. “It’s not the fastest or most expensive car here,” says Andrew, “but it does get the most attention.”
Anybody who knows about cars will instantly recognise this car as being a replica of the McLaren M6GT, conceived by Bruce McLaren as having the potential to be the first McLaren road-legal supercar, conceived decades before the McLaren F1. 
The original McLaren M6GT prototype was manufactured in aluminium. A mould was taken off this car and a further two bodies were manufactured by McLaren out of fibreglass. It is believed that another 100-plus bodies were commissioned and manufactured by Trojan, a small UK manufacturing company that built other McLaren bodies. 
The McLaren M6GT also came to be manufactured here.

McLaren begat Montage
One of the two previously mentioned fibreglass cars went on tour to the US in the early ’70s, where it was spotted by brothers Tim and Brad Lovette. At that time, they were already making a replica kit of the McLaren M8, called the Manta Mirage. They asked if they could ‘borrow’ the M6GT for a while and people responsible for touring the car agreed. It is not known if they knew the Lovette brothers were going to use it to make a mould but, in those days, second-hand race cars/prototypes had almost no value. Once they had made the mould, Manta Cars introduced a new VW Beetle-based kit car called the Manta Montage.
It was a very successful entry-level kit car and sold well. One of these Montages became a star of the TV series Hardcastle and McCormack (1983-86). No doubt, having a Montage seen during the show’s opening credits, performing stunts and high-speed chases helped sales. The highlight of each episode of the TV series involved a vehicle pursuit with the Coyote X (Manta Montage) chasing down bad guys attempting to escape in other sports cars. The show was similar in concept to the better-known Knight Rider TV series (1982 – ‘86), albeit not as high-tech.
Well-known New Zealand race car driver and designer Graham McRae visited Manta Cars in the USA and brought an unfinished Montage back to New Zealand with him in the late 1970s. Always the entrepreneur, he had the idea of producing and selling the car here. He approached David Harrod of Fibreglass Developments Limited (FDL), based in Feilding, about the possibility of producing the car in his workshops. 

Montage begat Mararn
His timing was perfect because for some time David had been considering building a car and seriously contemplated building a Cobra replica, but thanks to Graham, he got side-tracked into building the (M6GT) Montage which he called the Mararn. Working in his spare time, it took David about a year to strip the car and get it to the point where a set of moulds could be taken from it. 
Along the way, several modifications were made. The original car had door handles on top of the door which leaked and were perfectly sited to fill the door with water. David moved these to the side and fitted Leyland Marina units which looked better than the originals. A big issue was the poorly functioning door hinges on the Montage. David set about making a complicated double-hinge system with two different opening pitches that used rose joints. The result was extremely tricky to develop and it would send volume manufacturers back to the drawing board, but the final result on this already special car was worth it. 
A key problem was the car’s windscreen. At the time, Pilkington Glass was manufacturing glass for the local automotive industry in Lower Hutt. David approached them with the windscreen that came with the car in the hope that they could manufacture it, and after some thought they said that they could not do it and returned David’s windscreen, in pieces! David was not happy and demanded a meeting with the company board of directors. At that meeting, David insisted that as they had broken the only windscreen of its type in New Zealand, they were honour bound to replace it. They agreed, but It would take Pilkington more than 100 attempts before they were able to manufacture a windscreen that David could use.
Meanwhile, Graham had been offered the opportunity to be the chief mechanic of the USA Skoal Bandit Racing team, owned by well-known actor and race car driver Paul Newman. Given such an opportunity, Graham was happy to sell out his share of the car to David. 

The correct approach
Now that David owned the car fully, he decided to approach Ron Dennis ― the recently appointed CEO of McLaren motorsport ― for the rights to build the car. Ron was pleasantly surprised that David had approached him, as Manta had never asked for their permission. But his surprise did not extend as far as his wallet and he said that David could build the car if he paid McLaren a very large royalty with each car sold. This would have made the car uneconomic to build. A patent attorney was consulted, and he informed David that legally he would not be able to build the car until the 12-year patent held by McLaren Motorsport ran out.
With the rights still having a couple of years to run, the prototype was temporarily parked in a shed in the hope that McLaren would not renew the patent.  They didn’t, so in 1981 FDL started advertising the car, now known as the Mararn, one week after McLaren’s patent ran out. 
Steve Bond was employed solely to manage the car’s production, sales and advertising. He was given a budget and told that although making a profit would be nice, it was not the be-all and end-all. David was more interested in the Mararn being a showpiece of what FDL could manufacture. 
In 1982, with eight cars produced and sold, Steve Bond took on the role of overall manager. Of all the cars built, only the first three were turnkey, the first two built on a VW Beetle chassis. The third body was mated to a specially designed spaceframe chassis with a mid-mounted Ford 3.0-litre engine/Porsche 5-speed gearbox and transaxle for good measure. A total of 37 cars were built by Fibreglass Developments of which four went to Australia. 

Repowered
The example featured in this article started life with a VW chassis and was road legal in 1986, complete with fake fur headlining and bright purple metallic paintwork. The beauty of a kit car is that any owner can modify it. When the second owner bought it, the car was powered by a Mazda rotary. Not being fond of rotary engines in 2006, he got Fraser Cars to pluck it out and insert a Toyota MR2 subframe in its place. This they did very nicely by cutting off the rear of the VW floor pan and fitting a tubular spaceframe over the old chassis up to the front suspension to increase rigidity. The MR2 rear subframe, including the motor and 5-speed gearbox with the coil-over shocks, was bolted straight onto the new mount points. Andrew bought the car off the third owner Steve Clare in 2010. Steve had spent many hours tidying up the ripples on the body before painting it a more appropriate orange, manufactured and fitted the rear wing and the polycarbonate sweeping rear screen, not available as part of the kit from either Manta or FDL. 
After seeing it for sale, Andrew phoned Steve whose first question of Andrew was how tall was he? When Andrew replied he was 1.87m (6’2”), Steve said the car was not for him. However, on seeing the car Andrew had to have it, and managing to squeeze himself in he declared it to be almost comfortable. During 12 years of ownership, Andrew has only driven the car about 650kms. At the start of this year, he swapped the engine out and replaced it with a fully reconditioned Celica 3SGE 2.0-litre engine.
These days he has resolved to drive it more frequently. The fascination other people have for the car never grows old; a group will always gather to admire the car whenever and wherever he parks it. Getting fuel is always an interesting experience and seeing people of all genders draping themselves across it for a photo opportunity is not an uncommon occurrence. Like the other cars in his collection, the Mararn, although a favourite, is also for sale and should somebody be prepared to pay what he is asking for it, Andrew and the Mararn will part company. Due to his interest in the New Zealand manufactured car scene it will likely be replaced by another unique New Zealand car.

Last Tango in the Fast Lane

In the mid ’80s, I locked into a serious Nissan/Datsun performance obsession. It could have kicked off with my ’82 Datsun Sunny, though this would have been a bit of a stretch of the imagination, given its normally aspirated 1.2-litre motor — not the sort of thing to unleash radical road warrior dreams. But it did plant a seed, and it was a sweet little machine and surprisingly quick, in contrast to all the diabolical English offerings I had endured.
I was living in South Auckland at the time and was an unrepentant petrolhead. Motor racing was my drug of choice, and I followed the scene slavishly. Saloon car racing, with the arrival of the international Group A formula, was having a serious renaissance here and in Australia and Europe. There was suddenly an exotic air in local racing that had been absent for 15 years.
I was transfixed by this new frontier of motor racing that had hit our tracks in 1985–87 and the new array of machinery on display. In 1986, the Nissan Skyline RS DR30 made a blinding impression on me. The Australian Fred Gibson-run, Peter Jackson-sponsored team of George Fury and Glenn Seton were the fastest crew of the 1986 Australian Touring Car Championship. But Kiwi legend Robbie Francevic snuck through to win the Aussie Championship in his Volvo 240T after a strong start and consistent finishes.

Reincarnation of the snake
We are captivated by a top-quality sports car
The Shelby NZ build team at Matamata Panelworks has endured a long and challenging journey, culminating with the highly anticipated public unveiling of the 427SC and firing up of its sonorous V8 at the 2026 Ayrburn Classic Festival of Motoring in Queenstown on February 20. This is a New Zealand-built car with loads of character and potential.
The car is now back in Matamata, and I finally have an opportunity to get up close and personal with it. But before then, the question that must be asked is, “Why would ya?”
The first answer is easy, as mentioned in the last issue of New Zealand Classic Car (#404). It was a great way to use up all the surplus Mustang parts acquired while converting brand-new Mustangs into Shelbys. The unused new Mustang parts would be great in any kit car, but the 427SC in front of me cannot be classified as one.
This is not a kit car. The reality is that it is a high-quality, factory-made production car.
Possibly the second answer is because the CEO of Matamata Panelworks, Malcolm Sankey, wanted to build a replica of the car that is a distant relation to the Shelby Mustangs scattered around his showroom floor, a car created long before the first Mustang was even thought of, and the brainchild of Carroll Shelby back in the early ‘60s.
