AAMCO of Lake Forest definitely gets a five for service. I had to go back a couple times, but they were excellent in getting things done, so I can't complain! Car guys are difficult, but these guys were great. They were reviewing my transmission because I had some slippage. They did the transmission work for 15% to 20% of the cost that the dealership quoted. I also had some problems with a differential because it was making a strange sound like it was about to break. They fixed that for a tenth of the other quoted cost.
