Good friend of mine had one for 3 years, did le man for 3 years running as well. Only problem he had in the 3 years was a battery and a belt.
Very quick cars and i had the pleasure of driving it back from le man. If it had a better gear box it would have given my mates 360cs a good run but you lose a lot of time changing gear compared to the f1 box of the cs.
Takes some getting used to driving as its all low down power so your changing gear around 5500rpm.
Build qual was ok nothing special. Does get very hot in the cabin though and the windows only go half way down. Does have air con though.
In all in, i think they are a lot of car for the money they cost.
