Can sympathize. At some point you realize the car is depreciating in value no matter what you do, and live with scratches/dents. Heck no one else notices the small scratches but the owner after a big investment.

However sounds like you've just had a really bad run, especially since audio system should be good out of the box, and the windshield is just unlucky.
