The dealer explained that previous owner made some "modifications" and insisted that it is a gt3 from its VIN (ho humm). From your pics and description looks like they may have made a mistake...
Test drove it today, LOTS of power all right...but, now I know why you said that it's not a daily driven car
The price quoted has increased to near $70K (due tax) + my box, so I don't think I'm gonna get it unless I'm going to track frequently.
Thanks for all of your advice. It's good to know things in advance before making any commitment.
