Took my Subaru Forester for an oil change and tire rotation, also asked for help identifying why exhaust was being blown into the car by the AC/heater. Turns out my exhaust system had a crack, so I asked Tri-Valley to fix. (I knew would be expensive based on reading other Forester owner's stories about this problem.) When Don called Subaru to order the part, he was able to ascertain the issue was under an extended warranty, and he gave me a name and a dealer to call. I contacted that person at the dealer and ended up with over $4k of work done at no cost to me, due to the extended warranty and an additional recall on the vehicle. What a fantastic experience. Don is a true professional!
