Last winter I ran off the road and firmly planted myself in a ditch. No visible damages besides what the license plate holder did to the bumper as it broke off. This spring, I noticed my A/C wasn't working. It turns out that when I ran off the road, I cracked the condenser, so all the refrigerant leaked out. Basically, try checking the system for leaks. Oh, and the condenser ran me $330 installed.
EDIT: I hope to make it back up to plattsburgh for one of the future meets. I really enjoyed myself at the one in june.
