Thank you Denny and your great staff cuz it is a load off of my mind that my cars are always good to go after they have been in your shop!Services: Transmission

I called them at 12:30 on Monday with an emergency repair, I was house sitting and my jeep wouldn't start. Denny offered to take a look at it same day but couldn't guarantee they'd have the time to fix it. I had it towed over, and by 3:30 he called to let me know it was a battery issue and they were able to put a new one in for me. He also was able to send someone over to pick me up; Michael was great too. I was so, so relieved and beyond grateful. Since I'm in the area often enough I asked about getting regular car work done there since they showed me in that one visit they are decent and honest. I'm definitely planning to bring my jeep back!

We are a long time and happy customer of Denny and his team. They have proven time and time again that they put the customer first. Concerning this repair...it was a bit challenging as there were a couple problems and the second one did not manifest itself right away and it required a second visit to resolve. That didn't prevent the Performance team from making the repair quickly while at the same time keeping the cost to a minimum.Services: Air conditioning

I highly recommend Performance Unlimited for any automotive needs. The business is well run and operated by owner Denny Norton. His staff are certified well trained mechanics that are truly knowledgeable. It is appreciated that work to be done is detailed and courteously explained. Pricing is reasonable and honest without hidden fees. Again, highly recommended.Services: Auto engine diagnostic

Had an oil leak in my Mercury. Not only did Denny and his crew find and fix the leak, they were able to squeeze me in at the last minute. While fixing the leak, they also changed my spark plugs, potentially saving hundreds in labor Down the line. The cost, incidentally, was very reasonable. Just a joy to do business with. Highly recommended.Service: General repairs & maintenance

I have only spoken to the owner. He was very nice and more than accommodating as he allowed me to provide the parts and he just provides the labor. My first appointment here is Tues. I will update this further once I have services done there.
