im making myself a sports / westfield / locost / caterham car. My spaceframe is ready and i was wondering what donor car to buy.

What donor car is easy to work with?

Originally, i wanted to use a BMW 325i, because they have 200 bhp, a strait 6 engine and a limited slip diff. I have since been told that they would be a pain to work with.

Recommendations have been a sierra (in the haynes build your own sports car book) and a capri (from a friend).

This will be my first project so i want it easy to start with, but i still want it fast.

i do also have a limited budget, otherwise it would be cosworth all the way !!!
