I took my backup car that I seldom use in, expecting to have to replace both alternator and battery as that is what AAA test had shown. I had a little doubt about that as it had been starting each time after they jumped it but figured some sort of fluke. 5 Star retested, recharged battery and kept overnight, tested again and pronounced all fine. I had a little routine maintenance done while it was there but they could have told me much more was wrong. In addition the ladies in front were very friendly and knowledgeable and shuttled me back and forth.
