First car you're going to create?

Base model/Next trim level up

N/A 2.6 V8 and TT version for ultimate performance high-end models
Obviously to be cost-effective I'd have to put the engines in other vehicles as well, I was thinking I could stick the 1.5 in some basic compact/midsize sedans or hatches and the 2.6 could go in a light pick-up truck or small SUV, or maybe even a minivan. (Minivan with a V8? How cool would that be?)
Anyways, what do you guys think? Would you buy such a car? Have you given any thought to what cars you want to build?
