I was attempting to take my truck to a car dealership for trade in. It died at a stoplight, and I finally got it to start. I remembered Finzel's Mastertech had same day service on most repairs. I was able to get right in, and they diagnosed my problem. One of my two batteries was dead, and I had a loose positive terminal. They had me back on the road in no time and it didn't cost me an arm and a leg either. I feel that NAPA batteries are the best and that's why I went there.
