Brought my Honda Accord in for ac repair, the guys at aa fixed it right away and gave me a great price. I have found my auto repair shop!

This place is awesome. I was looking for a place near me that could perform an alignment on my 2007 Ford escape. The manager there (Don) gave me a great deal, presented me with excellent customer service and treated me like a human being. I don't normally post reviews but I was moved to do so after my experience here. Thanks guys... Richard Forte

I WILL NEVER TAKE MY CAR HERE AGAIN!!! I took my car in for an oil change and the next day I noticed something leaking on my garage floor. I took my car back and the owner proceeded to tell me that it was my "rack and pinion" and that "it needed to be replaced" right away at a cost of $1100! The owner was very apologetic and offered to show me what was wrong with my car (I am not a mechanic and would not know what I was looking at even if he did show me). I opted to take my car and get a second opinion and the other mechanic told me that THERE WAS NOTHING WRONG WITH MY CAR! He stated that someone had just spilled some oil all over the engine compartment and that my rack and pinion was just fine and had no leaks! Now I have to wonder if I was taken advantage of when I had Allstar Auto Center fix my brakes. The owner gave me the same apologetic song and dance that he would have to replace my rotors because they were in such bad condition. I went in there that time for a simple oil change and to have my tires rotated, and walked out of there paying $360. Now I wish I had asked for the old parts to know if those repairs were necessary.
