I am a Volvo Technician so I can not complain about my cost of repair. The car is a joy to drive. It is a very understated car. It will pull away from just about any average car at a light and it does not attract attention from police being a Volvo. It has plenty of storage room, very comfortable seats and ample room for 4 to 5 passengers. Common issues some suspension squeaks and rattles (spring seats, swaybar links and steering stops). Possible ac performance problems due to leaking evaporator cores. Over all the car has 140K + Miles on it and it drives very well. (I actually take the car to the local 1/4 mile track for fun)
Headlight wipers are great if you live up north in the snowy area. Heated seats are nice up north in the cold. Car is extremely solid car very good in case of an accident.
No improvements needed <--- Who is going to listen to me on future improvements on a car that was built in 1998?
