Mustang and Camaro give you a lot of power for a little money. May be too redneck though considering the other stuff you mention.
Me I'm happy getting to 60 in around 7-8 seconds. Every try a GTI? Ford Focus SVT? You can get a Focus for under ten g. Those things are fun.
Everyone and their dogs has a Mustang or Camaro in Oklahoma (including me ) Not interested in any fwd cars.
Ready to make a switch to a sexy, rwd, 6mt sports car.
Just not sure why I didn't fall in love with the cars I drove. The 335i was a fine fine car, but the turbo lag/throttle response wasn't as quick as I was hoping. And the 350z has a cheap interior, but that HR had a pretty exhaust note.
If I could find a nice black or solar orange 07-08 350z with 50k miles or less, I think I might be satisfied.
I know I need to test drive a Vette, but for some reason I just don't want one.
Actually tons of option it all depends on how reliable and practicable the car has to be.
If its just a fun weekend driver you could go for an mid 00s Elise, if you are small enough to fit in of course.
There are also loads of fast BMWs for that price, ranging from the classic E30 M3 up to the E46M3 and E39M5(by many regarded one of the best cars of all time), i guess you could also get an air cooled 911 for that price, maybe even a 996. E55 Amg or an B5/6/7 S4 convertible or sedan.
RX-7/8 or Infiniti G35/37 would be an option too.
Or you go American with the already mentioned GTO's, Vette's, Stangs etc.
BMW M3 / M5
Nissan Skyline GT-R
Some older Porsche...
Out of those i have driven S2000 & Supra (stock), S2000 is so god damn fun... very light RWD car with ridicilous handling and with its super high revving naturally aspirated engine (no turbo/compressor bullshit) makes it one of the most fun cars i ever driven... it has 240 hp from a 2 litre N/A engine, that HP per Litre is comparable to any Porsche GT3 or a Ferrari 360...
