Robert was very prompt in calling me and informing before the scheduled appointment that he was running late by 30 mins. That was totally fine by me. He very quickly could figure out that its the alternator problem, and had it replaced. He also told me that I need not pay for the alternator as it has a warranty on it, which I thought was really good. It saved me some money. And as a bonus, he lives close to me and would be the go-to reliable person for my car issues in the future.
