All on the books of course
But yeah, short answer: Kim's work was amazing, however I'd still never trust anyone with my car (well, when I had the 33) short of a mechanic who deals with performance cars every day.
I'm fairly sure in the entire time I owned my 33, the only people who took it for a drive that I know of were Paul from Autotech and Chris from Inline. Glenn/boys from ESP may have when it was being tuned etc, but yeah...I hate the idea of anyone driving my car, especially when it hasn't had bitch-limits put on the ECU
