The 3 series will last you the longest, will be the fastest(0-60 in 6.4 seconds) and will be the most comfortable.
The 944 is by the coolest, and its a porsche! but it has some reliability issues if your not careful.
The Datsun is the prettiest I think, looks like an old E type but it'll be the slowest running 0-60 in 9.3 seconds.
