Lawrence County, MO
Our shop is in Monett, so Lawrence County gets the shortest drive times for mobile and roadside calls. Visit our Monett page for directions and hours.

Our home base is a single shop at 100 Dairy St in Monett. From there we handle in-shop repairs, mobile mechanic visits and roadside help for drivers and truckers within about 50 miles.
Se habla españolDons Diesel & Auto opened in Monett in 2022, and nearly every customer we've worked on since lives or drives somewhere in southwest Missouri. Some come straight to the shop. Some call from a farm lane, a job site, or a parking lot with a truck that won't start. The service area below is simply where we're able to help in a reasonable amount of time.
There are three ways we work. In the shop, we handle the bigger jobs on cars, diesel pickups, commercial trucks and semis. Mobile mechanic visits bring tools to your home, farm or business when the vehicle can't easily make the trip. Roadside assistance covers jump starts, tire help and on-the-spot repairs when you're stuck. Mobile and roadside calls run during business hours, and we don't offer towing.
Distance matters most for mobile and roadside work. A shop visit is open to anyone willing to drive to Monett. If you're near the edge of the circle, call before you assume you're out of range. Se habla español.

The same eight services are available to every county above, either in our Monett shop or where your vehicle sits.
A straight-line circle on a map doesn't capture how people actually drive here. Some spots that look close sit on slow county roads, while towns farther out along US-60, MO-37 or I-44 can be quicker to reach. So the 50-mile figure is a guide, not a hard fence.
The easiest way to find out is a short phone call. Tell us the town or the nearest crossroads, what the vehicle is, and what it's doing. We'll say whether we can come out, whether it should come to the shop, or whether you'd be better served somewhere closer. Hours are Monday to Friday 8 to 5 and Saturday 8 to noon.
We serve roughly 50 miles around our Monett shop for mobile and roadside work. If you're not sure you're inside that circle, call (417) 205-3705. No harm, no foul.
