I recently took my vehicle to Hill's after an assumed engine problem. They shop that originally made the diagnosis did not seem very trustworthy. I chose Hill's because they are engine rebuild specialists. My problem turned out to not be the engine at all... They even asked permission to keep my car an additional day to further test it for hidden problems. None were discovered, but they didn't not charge me for the additional labor hours they spent tinkering with it.
They don't only do engine work, as my problem was related to the cooling system. When I had a problem, I called them and they told me to try a $10 at-home fix, and if that didn't work, bring my car in. I am very grateful for the knowledge, friendliness, and motivation for cars to run right, rather than them get paid...
I would recommend them to anybody, and will be taking my car there as long as I am in this town.
