I had been going to Luttrells for years, normally just getting oil changes and such, when I had a rumbling noise coming out of my engine compartment. I took it to them, and they said it would cost a whole bunch of money (nearly a thousand) to fix. I took it to another shop in town, and they simply cleaned of my belts and tensoners and solved the problem. \r
I now do not trust Luttrells to not rip me off.
