Mine was bullet proof until the 70k mile mark. Most reliable car I'd ever owned, only one unexpected repair costing more than $100. Once the 70K mile mark was crossed, nearly everything let go. And this was a car that although driven year round, was only taken out of the garage on weekends. But what I didn't factor in was that 70K year round miles that include very tough winters and very hot summers are a lot tougher than mild weather mileage. People who are considering a water-cooled Porsche with high mileage should bear in mind where in the country the bulk of the car's mileage occurred.
These cars are reliable but were not engineered for year round, four season long-term durability. And the cost of repairs do not scale down with age.
Mine is only driven in summer...maintenance is pricey but what a great car when it's running great!
