As I've written in other posts.....my 20 yr old (1998) Boxster (beautiful) with 85,000 summer driving miles has only needed a new water pump and coolant tank in the 16 years I've owned it. With so very little work needed, I feel fine with spending the money with my "indy" shop, especially since I have no desire, place or expertise wrenching on it myself. So in those 16 years I've spent an average of about $130 per year (other than oil/filter changes)...........very very reasonable for such a fun and beautiful car.
