There's a Don Foshays in Damariscotta, too. A bit closer to Rockland than Brunswick is.
There's a little shop in Damariscotta called Quick Turn. My mom got new tires there for her outback, and they aligned it for $40. Not sure if that's a package deal with buying tires or what, but it's definitely worth giving them a call. That's a damn good price, and they did a nice job. I was under there a few weeks later replacing a broken endlink, and everything looked good.
