TWR

There are clues aplenty that this is in fact TWR/018, the genuine V8-engined Rover 3500 SD1 V8 Group A racer built in late 1985 / early 1986 by Tom Walkinshaw Racing in the UK. It was freshened up in Christchurch in the early 1990s by recently retired and relocated TWR engine guru Allan Scott. It is now owned and regularly raced here by keen Wanaka-based classic car owner and driver Allan Dippie. 
Dippie is an active member of the largely South Island–based Historic Touring Cars of New Zealand group which, for the past few years, has been running the increasingly popular and well-supported Archibald’s Historic Touring Car Series.
With so many shells built into race (at least 19) and rally cars (as many as another 13), finding a pukka TWR car for sale has never really been a problem — in the UK.
