Very honest mechanics and that is very difficult to come by. After going to car dealerships and having my car checked out, I was told certain jobs needed to be done and was quoted astronomical numbers. I immediately called O'neils and was quoted at half the price! I took my car in and he came back saying not everything the dealership was going to charge me for needed done, so he saved me even more money when he could have taken advantage of me. Very honest guys here that do great work and I don't take my car anywhere else anymore. I highly, highly recommend.
