Wow, great find and at the best possible price!
Where in SC are you? I have a local indy mechanic in the Florence are that has worked on my Z4 and is very reasonable.
You are going to love that car. That is what I always wanted but never had the money for....
Then when time finally came to buy one I ended up getting a Z4 because of the glass window on the soft top. But I still think the Z3 is an amazing looking car.
