When I got the AC refilled on my old GXL it cost just over $300 at jiffy lube. The system was dry no freon at all. My friend hooked it up for $50 bucks, though. I feel guilty drivning witht AC on in traffic especially b/c the engine as to work soo hard... poor thing. My car was black too so even though it blew out freezing air the car's temperature never seemed to really get low.
