I had some bodywork done on one of my classics at Lake City Autobody in Gilford. They have a mechanical side of the business and while I was there, I saw an early 70's Buick Skylark getting engine work, an early 50's pickup belonging to Gilford Well (restored), and a few other antique cars in for tune-ups, brakes, etc.
I dealt with the GM, Bill, and they did a fantastic job. Looks like you could eat off the floor of the place, too...
