While visiting Circle C feed store just south of Sheer Automotive, My 20 year old Tahoe wouldn't start. The guys at the feed store called Sheer to see if they'd come down to help me. The man from Sheer showed up in a short while and he found the battery was shorted out. I needed a new battery to replace the 3 year old one. All done in less than an hour. It cost me about the same as the defective battery had cost originally. I couldn't be more pleased. This seems to be the best shop around. They'll have my business from now on.
