Clark's is in a strip mall with several other auto repair places, and is actually part of BelKirk Body, I believe.
I've been to Clark's three times, twice in the last year and once several years ago. Each time I made an appointment, dropped the car off, and got it back between an hour and 90 minutes later. Each time the driving was improved quite a bit, and the price was very low for my particular car.
A word of explanation. If your car is out-of-alignment, the steering may pull a bit one way, or the feel may be a bit mushy. A lot of people, including my wife, won't notice mushy or pulling, but the tires do - they wear unevenly and early - and exuberant drivers will. Alignment can be knocked out by big pot-holes, hitting a curb or being rear-ended and having to get the car straightened out a bit.
My car is a bit pricey to align because it's a European all-wheel-drive model. The dealer charges about $129 to do an alignment. Clark, for the same car and a great job, charges barely over half that. Two-wheel-drive cars should be less. And they do it quicker than the dealer.
Another advantage, but a coincidental one, is that while waiting you can grab lunch at the nearby strip malls, which have several mediocre teriyaki places, a Pho house, Thai, Chinese and Mexican on the same block. That may sound silly, but it helps kill the time.
