I use Black Forest in Mt. Pleasant. Only complaint is their prices for parts are 40-45% higher than Phil. But that is the cost of doing business East of the Cooper. Their work is first rate though. I had them do the dreaded a/c evap. replacement on the wife's TE worked out well.
I have also used Star Motors West of the Ashley (on Bees Ferry Road). They are also very reliable & fair.
Hope this helps.
