Honest diagnostics
We tell you what’s wrong before we fix it. Clear quotes, no surprises, no upsells — ever.
Honest diagnostics, experienced technicians, and serious performance work. We find the problem, explain your options, and give you a clear estimate before repair work begins. Nothing gets done without your approval.

Dave opened DMS on the Indianapolis Westside in 2020 after years of watching drivers get handed inflated invoices for work nobody explained. The shop was built to be the opposite of that: you talk directly to the mechanic, you see the problem before you pay for it, and nothing gets touched until you say go.
Since then we've repaired more than 7,000 vehicles for people across West Indianapolis, Speedway, Ben Davis and Plainfield — most of them sent by someone we'd already looked after. We're ASE certified, we work on domestic and import, and every repair leaves under warranty.
Dave also builds and races his own car on the track. That hands-on experience shapes how DMS approaches calibration, heat management, brakes, suspension, and every supporting modification around a performance build.
