I was having a problem with my car starting. They weren't entirely sure the reason, but they were going to try something and see if it worked. At this point I am unsure if it worked, but they let me know the risk upfront. I have been here a couple of times (we have very old cars with a lot of miles) and have found that I can trust them, so I keep coming back. I would have given 5 stars for this visit, if I could be sure the fixed worked.
