I'm toying with the idea of trading my C4 for or toward a C3.
It's an 88, 107k miles, auto, red with black leather interior, mostly stock. It has a brand new catback system (adjustable PowerEffects). It could use a paint job though.
It's my daily driver (3 miles to and from work is about it), so I would say that it's extremely reliable. I love the car, I'm just more partial to the C3 body style.
If anyone is interested, email me at jwebb@acs.ac or instant message me. I'll answer any questions.
