I say get one when you can but for the money he is asking this one seems a bit run down.. and the Turbo isntall would scare me away.
But don't stop looking!! there is a 911 out there for you that is in better condish... trust me.. never buy the 1st one you look at unless it is a great car.. it took me 6 months to find my SC... and i had a love for everyone I looked at before i bouight mine..
