Huge doubt

I've severe doubts about my next car...

I've a few that I like...BMW 320d from 2006, BMW 320d Coupé from 2007, Mini Cooper S from 2006 and Alfa Gt 2006.

What I like the most? BMW 320D Coupe but it's also the most expensive.
Alfa GT seems to be the same price as the 320D berline but GT is much pretier...Althouth probably less "car" than the 320D berline...

Mini Cooper S is a toy car, I would buy it only if I find a really cheap one.

What do you guys thing I should buy?
