LOTS of road noise. LOTS of wind noise on door windows. Lots of noise from seat belt parts clanking inside the door posts.
Volvo should be ashamed for such lousy seats. They know how to build great seats but they shortchanged the V50.
Cheap glove box door and locking mechanism. Lots of shortcuts on the interior materials including the headliner and seat parts.
Terrible due the road noise and drivetrain noise.
Too cramped. See previous comments about seats.
