Just a thought really - I know someone on Passionford built a "new" Cossie using a 3-door shell, and it ended up on a Y-plate :cool:
So, given that for it to have a new plate it has to be like 95% new or something, can you buy everything that you'd need?
I'm guessing you'd need:
shell + all exterior lights, plastics etc
all suspension
wheels
engine + associated bits
interior
From what I can tell, the shell's £1500, the suspension is about £1k (going from my widetrack conversion), wheels are £800 if you get willy wheels, interior is probably pretty hefty...
I reckon the only serious, serious outlay would be the engine.
If you did it yourself I reckon you could get one on the road for under £8k?
