Auto Repair in Kinnelon, NJ — Your Trusted Local Mechanic Since 2008

RSW Auto Repair was founded in Kinnelon in 2008 and has operated at the same address — 1167 Route 23 South, Kinnelon, NJ 07405 — ever since. This is not a chain with rotating technicians, and it is not a franchise. It is a family-owned shop that grew up in Kinnelon, has stayed in Kinnelon, and serves Kinnelon residents as neighbors — not as customers passing through.

Over 18+ years, that consistency has built a reputation: 4.7 stars across 210 verified Google reviews from drivers throughout Morris County. Kinnelon drivers know they can count on RSW for honest assessments, first-time-right repairs, and a team that will remember their car the next time it comes in.

Kinnelon residents have options when it comes to auto repair. Here is what keeps them coming back to RSW:

• Kinnelon's Hometown Shop Since 2008

  Same ownership and team for over 18 years on Route 23. Not a chain, not a rotating crew — a local shop that has grown alongside the Kinnelon community.

• European Car Specialists

  Specialized experience with BMW, Mercedes-Benz, Audi, and Volkswagen alongside full domestic and import service. Most shops in the area do not have this depth.

• Digital Inspections with Photos

  We send photos and inspection notes directly to your phone during the visit so you see exactly what is being recommended — and why — before approving any work.

• Transparent, Honest Pricing

  Written estimate before any work begins. No surprises on the invoice. We tell you what your car needs and what can wait.

• 3-Year Warranty Option

  Qualifying repairs are covered for 3 years or 36,000 miles. Ask your service advisor which repairs qualify when you schedule.

• Same-Day Availability

  Most common services and diagnostics can be completed same-day when you call ahead. We work to accommodate urgent repairs quickly.

Kinnelon is one of Morris County's more affluent boroughs — and it shows in our service bays. BMW 5 Series, Mercedes-Benz E-Class, Audi Q5s, and Volkswagen GTIs are a daily reality here. European vehicles require a different level of diagnostic access than most general shops are equipped to provide. RSW was built around European repair from the start.

Our technicians use factory-equivalent diagnostic platforms — not generic OBD-II readers — to access the full depth of BMW, Mercedes-Benz, Audi, and Volkswagen systems. That means dealership-level diagnostic capability with independent shop pricing and a direct line to the technician working on your car.

  Engine, drivetrain, and ISTA-level electronic diagnostics for 3 Series, 5 Series, X3, X5, and more.

• Mercedes-Benz Repair
