Honest gas & diesel repair, right here in Rapid City.
Owner David Duchesneau answers the phone himself, no front desk in between. Diagnostics, engine and transmission work, brakes, tune-ups, and quality pre-owned vehicles for sale.
The shop
One mechanic. No middleman. No upsell.
David Duchesneau answers the phone personally, so you get a straight answer instead of a front desk guess. His reviews describe him going out of his way for stranded travelers passing through on I-90 and near Custer State Park, working on his own time to get people back on the road.
He is known for pricing well below dealership quotes, in one case for half the price of a dealership estimate, and for not adding on work a vehicle does not need.

Reviews
What Rapid City drivers say
“This man is god-sent!!! BEST MECHANIC I have ever dealt with in my life. My car broke down on vacation in South Dakota and blew its engine. Dave did it for half the price!!!! He even changed all my fluids without charging me.”
Philipp Wobig
“BEST mechanic I have ever worked with in my life. David answers the phone personally, you skip the front desk person who does not know anything. He DOES NOT overcharge or upsell items and work. He took my truck in, on his own time, to get me on the road again.”
Blaine Angstadt
“David was able to slot me in with minimal waiting and clear communication. He welded my flex pipe back together after I checked out the mountains, for an insanely reasonable price, and charged up my AC as he was driving out the door.”
Kenneth Nichol
“We had an issue with our brakes while we were in the middle of nowhere at Custer State Park. David was incredibly helpful. He followed up with us afterward to check that everything was okay.”
Feno Hanitriniala
“Affordable, friendly, efficient, and most importantly, honest. David is a great guy and mechanic. He replaced the transmission on my 2008 Chevy Suburban and had it back to me in less than two weeks for a more than reasonable price.”
