Inlaw has offered to let me drive the beast he has, the Super Snake, only 650 Horsies.. I've declined, so far, way too tempting to run it up over and over! BUt have ridden with him at the wheel, pretty amazing how quick you can be up to 130+ on a little country road... Serious toys! When they did the upgrade it was new blower, new hood, wheels, solid alloy driveline, as well as other goodies... My guess is he has near $80k into it... Bought it cheap as a newer one came out, but added on a bit...

Real serious owners have taken them up over 750 hp... but for a production car, with warranty to go out at his 650 and now the 660+ is interesting...
