Todd Pollard

Was able to get my vehicle in and repaired in a timely manner and at a reasonable cost, other repair estimates were much higher for the same work

Todd Pollard

First off, if I could give more stars I would.

Second, this is the greatest experience I have ever had with a mechanic. I took my wife’s 1989 Chevy Silverado with a blown motor, after several shops said it would be $10,000. Harold did for half the cost and was completed in 3 weeks. He is the best! He always was letting me know what was going on and no surprise costs. He also installs scissor door on autos, so I know what my next project is going to be. Couldn’t be happier with the way the truck is running, only has 30 miles on it so far but everything is perfect. Most importantly my wife is happy!

Dalton McMurray recommends Top Speed Performance.

I took my 300 here to have it looked at. They did a very thorough inspection. Ended up having all new suspension done and he did an amazing job. I would 10/10 recommend his quality business and customer service.
