I brought our car in for an AC problem (which they diagnosed) D&D notice a very dangerous front tire that I was unaware of, called and sent me pictures of the HUGE bubble coming out of the inner side of one of the tires. It was really big and would have blown at any time. They replaced the front tires and didn't charge me for the AC Diagnoses - (which they will repair shortly). Careful, reasonable and pleasant to deal with, all of which make it a bit more palatable when you have to spend a bunch of money on something that (I at least) would rather just keep magically working...
