I bought my C70 used with about 50K miles on it about 5 years ago. I love the way it looks, and love the way it drives even better. It is surprisingly quick for a Volvo. I had to replace the throttle body twice, but Volvo has covered it as a recall item, so it was on their nickel. I have had it in the shop for only one other significant issue. The mass airflow sensor went out while I was on a road trip and rendered the car not driveable, which was not at all convenient, but at least an easy fix. Overall, the reilability has been great. It definitely has been a great car for me.
Fun to drive. Great looks. ProLogic sound system. Reliability. Big trunk.
The back seats are actually pretty roomy for an adult, considering it is a coupe, but the electric seat motors for the front seats are painfully slow.
