Reviews
What Drivers Say
"Had my Cascadia in for a PM and a DOT inspection. Dropped it at 7, picked it up before lunch, and the invoice matched the estimate to the dollar."
"They tracked down a wiring problem two other shops gave up on — and showed me the burnt harness before they fixed it. Straight shooters."
"Saturday hours are why I tried them. Brake chamber replaced while every other shop in town was closed — back hauling Monday morning."
