Performance Unlimited is the only place I will have work done on my vehicles. Plain and simple it comes down to trust and I never have to worry about whether my vehicle will be fixed correctly the first time. I trust Denny and his team at Performance Unlimited! End of story!

We have been taking our cars to Denny at Performance Unlimited for quite sometime now and ALWAYS receive the best service! Denny is always honest and fair when taking care of our cars. Most of all, he cares about our safety, and wouldn't let us drive away without knowing our cars are in top notch working order! If you are looking for an auto repair shop to give you peace of mind, we highly recommend Performance Unlimited!

I have been using Denny Norton's services for many years and found the quality of repairs and quote accuracy to be second to none. He loves cars and the people that drive them. He has a family owned and operated business where every employee treats you with the same level of respect that Denny does. My Ford has over 200K miles and I expect to have it running like new for many months to come thanks to the excellent service provided by the skilled techs at Performance Unlimited.

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!
