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.

Bronze treasure unearthed

The car was put away in favour of something more practical, and when his father was unable to drive any more, Matt’s friend asked him to come and take a look at his dad’s old Holden. It turned out this was one of those phone calls that leads to that feeling of pure joy in the classic car world — the ‘barn find’ that turns out to be even better than expected. The HT Monaro had been put to bed some years before and had not seen the light of day since. Layers of dust and boxes of junk littered her undercarriage and bodywork and access points all around.

A bit of TLC that became a major restoration
The 1302S, or ‘Super Beetle’ as it became known, was built for two years before it, too, was replaced by a further-enhanced Beetle, the 1303, continuing an amazing 65-year lineage for one of the World’s best-known shapes.
The world’s best-selling single-model vehicle, the VW Beetle, possibly established another record for the amount of controversy it has created since the inception of the Type 1.
In a meeting with Hitler in June 1934, Ferdinand Porsche was contracted to build a ‘People’s Car’ that could accommodate two adults and three children, was air-cooled and simple to maintain, and could cruise economically at moderate speed along Germany’s proposed new Autobahns.
Our feature car, a 1972 1302S ‘Super Beetle’, was found by Dave and Michelle Dickie in Mosgiel a few years back. It was a runner, but like most VWs of this age, it needed a little TLC. They were looking for a daily driver for Michelle when they first came upon the VW being sold locally on behalf of its owner.
“The owner offered it to his grandchildren, and they didn’t want it, so he got the guy out at Mosgiel in the Mobil petrol station to sell it for him, and he put it on Trade Me for them. We never met the owner, and we were always dealing with the guy at the petrol station. We put a bid on it, and we were the only people that bid on it.”
Their bid was eventually successful, eight years ago. Not knowing much of the history, in situations like that, it’s always a risk buying a car, but they were in for a bit of a surprise.
