What would be good? For me, either something jap or something silly.
Doesn't have to be too fast, nothing too exotic parts cost wise. My thoughts were Tatty Mk1 MR2 with ticket. Volvo 340 1.7 (usually immaculate due to one giffer owner rwd not as slow as reckoned, pretty hard to break). Volvo 740 turbo saloon (cheap because it isn't an estate, will take a manual boost controller for some extra oomph, rwd). My brother who fancies going halves suggestion was an Escort SI. Nothing else, just an Escort SI. No other car on the planet comes close to providing the performance, parts cost and handling per quid than an Escort SI in his world and he would be happy to trailer it behind his Shogun. Or maybe a Nova at a push. He has no imagination.
This would be something that would have almost everything inside that isn't needed for the MOT stripped out plus a couple of speakers and radio for the times we drive there rather than tow, and a pair of bucket seats. trackmods would be a fresh pair of shocks and some lower stiffer springs, plus one box removed from the system and replaced with a length of pipe, plus a hollowed cat if it pre-92, and a homebrew cold air intake. Simple mods to free up breather and body roll.
I really like RWD, but for some reason he wants a FWD blue oval.
