After a few 911's I think in this next year I am going to purchase a 360. I am wanting some help as far as service etc. If I buy a 2000 or so car with 20K on it, that seems to be my price range, what should I be careful of ? What servicing is required and cost? Is there any real performance difference between a F1 car and a Six speed? I would have never considered a tiptronic in a 911 but there seems to be more F1's than six speeds in the 360 series. I am considering a coupe not a spyder. Thanks for everyones input.
