Poor customer service, rude
They didn't fix the issue and the guy behind the desk was very rude when I asked why. Never again.

Quality diesel repair shop
They know the Cummins engines well. Good communication about parts and costs. Only minor gripe is the shop is always busy.

Decent service, bad timing
They do good work but they are often behind schedule. Make sure you call ahead for updates on your repair.

Good repair but expensive
They fixed my engine right, but the bill was higher than the initial quote. Make sure you get everything in writing.

Misdiagnosed my engine problem
They charged me for a repair that didn't solve the issue. Waste of money and time. Very disappointed in the outcome.
