I'll just repeat what I've said elsewhere:
101hp and 170kg dry. No trick transmission. If you add the race kit to get 212hp, it meets no emissions - either sound or exhaust, and you probably couldn't pass the meter at 'Bogie. It is illegal on the street at full power, and the full power isn't spectacular. Nothing is replacable at a reasonable price, or is irreplacable, period.
Errrrrrr, no thanks.
Think I'd rather buy a new diesel truck, upgrade my toy hauler, pick up two RSV4 RRs with track package, two ZX6Rs, a big tupperware box full of track spares and lots of vinyl logos to put on everything, with the team name of "RC213V-S Racing". Then I could tell everyone that my whole operation cost less than a RC213V-S when they asked.
I'd even have a 200hp+ V4 out of the deal. Er wait, two of them. And a couple 600s. And a diesel truck. Air conditioning and a fridge at the track. Power canopy. Cold beer. A place to shag at night.
Just sayin'
