2001 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl 4A)
List of problems: EGR value replaced at 40k miles ($410), multi-function switch replaced (for faulty wiper blades) at 43k miles ($530), replaced brake rotors at 44k miles ($300), new catalytic converter and transmission at 53k miles ($4,900). Sorry to say, this has just not been a reliable car at all.
Plenty of leg room and head room. I'm 6'3" and don;t feel cramped at all in the car.
