gsxr750

Best thing to do is to drive all the american and japanese muscle and sports cars. I test drove all of them a few months ago and the standard base corvette blew everything out of the water. I almost bought a 2012 vette but it was damaged by detailers at delivery. I bought the 370z the next day $15K less that the vette.
Heres a summary of what I found after driving all the High Horse Power Muscle & Sports Cars.

1. Base model vette best overall performance appearance inside and out, poor reliabilty over the long run.
2. 370z better handling than the vette, great appearance and design, best reliabilty, more than enough power.
3. Camaro ss 430 hp best looks and appearance inside and out best power and handling of all the 3 muscle cars, back seat a real plus.
4. Dodge challenger rt 5.7 375hp manual, love the old challenger looks dodge nailed it on the outside, buy on the inside it looks like a work truck really plain, handling good in a straight line, it really didn't seem like it hade 375hp when driving it, more like 275hp.
5. Mustang GT, seemed a tie with the challenger, on the outside the mustang looks great, and on the inside it very boring or plain, performance a liitle better than the challenger. Then you have fords reliabilty issues.
6. Mazda RX8 , I really lliked this car in styling inside and out , it kind of reminds you of one of the old shelby cobras lemans hard top cars, ( not a mustange corba). Handling was also very good and the rotary engine reminded me of riding a 600cc sport bike , you can have a ball reving the engine to redline and shifting at 10k all day. Even with only 220hp it is surprizingly quick. Its to bad they don't make a 350 hp version of the RX8.
Then there is the connection to ford, I never really cared for fords, to many reliability issues.
