Very courteous, professional, and prompt. I brought my truck in with a stuck EGR valve and they fixed the issue, and were very hospitable to me and my dog while we waited for the service to be performed.

Went to the Kennewick branch — great customer service.

Total charged was $875 for them to bring me a battery and swap a fuse th... read more

Greatest Regret Ever!! Took my truck in for suspension service. When I got home. There were loose nuts and bolts EVERYWHERE. please don't take your car into this shop. Not unless you wanna see your tire fly across the highway.
