I've had my car (1990 964 C4) for over 6 years, It's be a great car with killer performance for it's year and awesome MPG, around 30 at 75mph. There great cars with lots of parts to upgrade.

With a half dozen years of ownership, I have to say that this is one great car. It does everything well and rewards the true enthusist with performance and personality. Engine, clutch, brakes, transmission are bullet proof. Amazing reliabity in the running gear, but HVAC is an engineering absurity.
