335i 300hp, 300lb-ft or 320hp and 332lb-ft
328i 230hp 200ft-lb
Mustang V6 315 HP, 275lb-ft
The V6 seems to be a pretty legitimate choice with good output, especially for the money. Same goes for the entries from Hyundai, Chevrolet and Dodge.
I kind of like the Challenger R/T. Reminds me of a gregarious, slightly overweight kid with middling marks that was everybody's friend and a pile of laughs in class.
