Don't really know anything about specific shops in the area, but about the best thing to check is for a local z club, they may have members that can check it out for you, or go with you if the car is local. When looking at the older cars, the main thing I look at is the overall condition of the whole body and undercarriage. Mechanicals are the least of my worry. This advice is moot if you're looking for a "numbers" matching or completely original car that has been restored and you would want everything to be in tip top shape. For example on my '73, it sat for 14 yrs and the only thing I checked was the condition of the body, it checked out and I was out the door with a very nice condition '73 for $500 not running.
