Don Swartz has been racing cars on and off for the past 35 years. Recently, the Grass Valley native and owner of Swartz Diesel used that experience to rise to the top tier of the Pacific Challenge Series, where he competes in late model racing.

Swartz showcased his racing acumen last weekend at the Pacific Series Challenge’s final points race of the season in Ukiah, taking sixth overall in the main event and winning the Trophy Dash race.

Honest and knowledgeable!

Had a problem with my truck while visiting nearby in Nevada City. Don is an honest man and knows his stuff. He diagnosed it over the phone, and when I limped it into his shop, he was able to confirm it and fix it to get me back on the road. If you're looking for an honest businessman backed by a couple of decades of experience, take your rig here. I can't speak highly enough of Don. He epitomizes what we all want to see in any business we visit. - Mike S.
