R And M Automotive is an independent repair shop that handles general mechanical work, diagnostics, and routine maintenance without the markup typical of dealership service departments. The shop operates with ASE-certified technicians and charges a labor rate of around $85 to $95 per hour, depending on the job complexity.
This is a full-service independent repair facility, not a quick-lube or dealership service center. Technicians diagnose and repair engine, transmission, suspension, brake, and electrical problems. The shop also performs oil changes, filter replacements, belt service, and preventive maintenance. Work ranges from straightforward jobs (spark plugs, air filters) to more involved repairs (water pump replacement, transmission flush). The diagnostic fee is typically $75 to $100, which applies toward the final bill if you proceed with repairs.
Labor runs $85 to $95 per hour. A routine oil change costs $40 to $60 depending on oil grade and filter type. Brake pad replacement ranges from $150 to $300 per axle, including labor. Transmission fluid service typically costs $120 to $200. ASE certification across the shop's technician team means diagnostic work meets industry standards, reducing the risk of unnecessary repairs. The diagnostic fee is credited to your repair bill if you move forward, a policy that distinguishes this from shops that charge diagnostic fees but provide no credit.
Call ahead to confirm current rates, as labor costs shift with market conditions.
Independent shops in Chattanooga like R And M typically charge 30 to 40 percent less per hour than dealership service departments, which often run $110 to $150 per hour. Dealerships justify higher rates with factory-trained technicians and genuine OEM parts, but for many maintenance and repair jobs, independent ASE-certified shops deliver the same quality at lower cost. National chains like Firestone and Jiffy Lube handle quick service efficiently but often lack the in-depth diagnostic depth R And M offers for complex issues. Choose R And M for cost-conscious repair of domestic and imported vehicles; choose a dealership if your vehicle is under warranty or you need factory-specific work like transmission reprogramming; choose a quick-service chain only for oil changes and tire rotations when you need results in under 30 minutes.
This shop works well for owners of vehicles out of warranty who want honest diagnostics without upsell pressure. Customers comfortable with independent shops and those seeking lower labor rates than dealerships benefit most. The shop does not specialize in high-end or luxury diagnostics, so owners of newer luxury vehicles with complex electronic systems may still prefer dealership service. Drivers with tight budgets who need routine maintenance or basic repairs find the best value here.
Call or visit in person with your vehicle's year, make, and model, and describe the problem or service you need. Staff will quote a diagnostic fee and estimated labor time. You can drop the vehicle off or wait while technicians run tests. Once diagnosis is complete, you'll receive a call with findings and a repair estimate. You then decide whether to proceed. For routine jobs like oil changes, you may not need a formal diagnostic; staff can often quote labor time immediately.
Confirm hours by phone before visiting, as shop schedules occasionally shift seasonally. Street parking is generally available near the shop. The facility accommodates most vehicles, though very large trucks may require verification of lift capacity before arrival. Call ahead if you're bringing a vehicle with known transmission issues or electrical faults that require extended diagnostic time.
R And M Automotive fills a practical gap in Chattanooga's repair market for vehicle owners who need reliable diagnostics and honest work at rates that don't require dealership pricing.
