Still slower than the Mustang GT, but then again, good luck finding a GT for the base price, they're almost all well into the $30k+ range with any options at all.
Yeah, good stuff listed here .. the obvious short list for cars that you can actually find new for under $30k would have these :
Miata (yes I know it's called MX-5, but that doesn't have enough personality)
Mustang V6 Premium (.96g grip and 0-60 in 5.1 never hurts with proper FR fun)
WRX (very effective, though AWD kind of cuts the power oversteer fun)
GTI (not that great stock, but it's fairly light and easy to mod, I don't care for FF though)
MS3 (ditto the GTI observations, but a bit better stock v stock)
Genesis 2.0T (a little heavy for the power it has, but good driving dynamics)
Open the thing up to lightly used, and the options flood open, $30k will get you CPO or almost unused very low miles stuff like this :
'11 Mustang GT (super hard to find used right now, but some program vehicles or broken lease vehicles trickle by)
370Z
STI / Evo
G37 Coupe 6MT
Camaro V8
Challenger V8
135i
335i
