Took my car in for a tire rotation and oil change, and was told my oil case gasket thingey is leaking. Normally I would say, "LIAR!" and run, but I knew it was true because there was a puddle of oil under my car all the time and I've already had the head gasket replaced. They fixed it same day, quickly, with no fuss, and since then, no more oil leaks! Yay! This does seem like an honest place.
