You could buy a Soarer TT, in standard form 155mph but not the most inspiring sight, but pick a good'en for 5k and spend 2.5k and you have one like mine.
370hp
360ftlbs
1700 Braking HP brakes
265's rear 235's front
0-62 5.0
0-100-0 in less then 15secs
12.2 quarters
8200rpm
18mpg (the bad bit hidden in the good)
1g lateral grip
Trackday suspension (if fitted with TEMS) for the grand price of 2p!
Complete anonimity (the police wave you on, in the 3 years I've owned my baby I have never been pulled by the filf, in my DB7 is was a monthly occurrance, I drive fast and used to receive dozens of warnings, the Soarer is much faster than the DB7, but she is invisible, still no points on my licence)
It is quiet and soothing same setting for the stereo at 130 as at 30 yet will kill almost anything out there .
I'm a fan, so I'll shut up before I get flamed for being here.
I forgot the 'comparison' bit, well if anyone wishes to drive my car against their Skyline then they are welcome to, I have driven both, but driving is a personal thing.
Apologies.
