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. I mean, why pump hot air from the engine when you could just run the hot oil (already passing by) through a 3-way valve and coil under the dash? And how many yards of leaky refrigerant hose do we have as it runs from one end of he car to the other? And those 5 servo motors in place of a few manual slide valves? Sorry. The HVAC is dumb.
Performance, looks, sound! No cupholders.
Have GM design HVAC. Leave speakers and sound system in dumpster with German HVAC system.
