it's detuned. i paid $400 for mine, and i've been driving it daily for over a year. i gutted the interior, everything except console, dash, and driver seat. i love mine so much, when this disposable car goes, i'll buy another.
usual things, ie: timing belt/waterpump, etc.
it's a blast to drive, but i'd probably go for an "i" if i wanted more go. even still, with shedding the weight, it feels faster than my SC did
