I'd go for a detailed one for sale - the doors would have to open and it would have to have an interior, though. I had an Lotus 7 restoration (that I sold unfinished) in addition to a Mini Cooper, plus a Lotus Elan (think Emma Peel), that is a another car you should do! Europas were actually pretty dreadful cars, incidently, no speed and the (early ones) didn't have opening windows!
