There are cars famous for high mileage and longevity. Matt Farah's million-mile Lexus LS 400 comes to mind, as does Irv Gordon, who put over four million miles on a 1966 Volvo P1800. But a Porsche 944 with 571,000 miles? At first glance, that seems like an exercise in self-flagellation.
That's not to say it isn't possible. As sports cars go, the Porsche 944 was comfortable and economical, getting close to 30 mpg on the highway. However, the car is somewhat maintenance intensive, requiring frequent timing belt servicing and having a reputation for water pump failures and electrical issues. It's also not an easy car to work on, even for the experienced DIY mechanic.
