What to look for in an alignment shop?

Asked other folks around with old cars where they go. Forget about the chain stores all they mostly touch is toe setting on new stuff. I found an old shop and asked the owner about setting up my car after two goodyear screw ups. I explained everything was new and not to change the ride height I had set. Car drives like new. I immediately made another appointment for my other car. I happily paid the $90 it cost per car.
