I went to them to purchase a sensor for my Jeep Grand Cherokee. When I explained to them what was happening when I started my car they offered some great advice and came out to my car to test the electrical system. After testing for problems with the Alternator and battery, they found my sensor was OK. They replaced the battery, installed it and charged me nothing. My old battery was under warranty and they handled everything. I didn't need a receipt they looked up my battery purchase from years ago when I bought it. The staff was knowledgable, friendly and caring. This was a great experience.
