97 Boxster, should I buy?
 

I'm 16, and looking at this Porsche Boxster.

I can't really tell much from the add. Not great pictures. Is $6900 a good price? Is 120k a lot for this model? I've heard that repairs are expensive, but I can do a little work with my dad at home. I know insurance would be high for a teen with this car, but my dad said he could just put it in his name until I go to college. Is this a good deal or a scam?
Any help would be greatly appreciated!
