2003 Porsche Boxster S 2dr Convertible (3.2L 6cyl 6M)
The car is the closest to perfection there is out there. The Boxster will outhandle anything out there now. Road and Track did a slalom run in which it blasted the Enzo's (the Ferrari guy costing $700K) record. True it does not have an overabundance of hp's but once you pounce on the accelarator you get usable power with unmatch driving dymamics. With a top speed of close to 170 mph I think it is fast enough.
Engine music as you drive up through the gears. The driving dynamics, sensation and feedback are all perfect.
Bring the Boxster S to 300 hp. The interior has been revamped this year so no need to tamper with it.
