Our services

Every make. Every model. Whatever it's doing.

If it drives, we work on it — and if a job genuinely belongs with a specialist, we'll point you to one we'd use ourselves.

Massachusetts state inspection

Safety and emissions stickers six days a week, first come, first served. Bring your registration and plan on well under half an hour.

Brake repair

Pads, rotors, calipers, hoses, and fluid flushes. If the pedal is soft, low, or noisy, don't wait for the next sound.

Check engine light

We pull the code, then chase it to the actual fault. Replacing whatever the scanner names first is how people end up paying twice.

Oil & filter change

Conventional through full synthetic, plus a look at belts, fluids, and tires while the car is up on the lift.

Tires

New tires ordered and mounted, plus rotations, balancing, patches, and pressure checks. Air is always free at the pumps.

Suspension

Struts, shocks, bushings, and control arms. New England potholes take a toll — we'll tell you what's worn and what can wait.

Steering & alignment

Pulling to one side, a wandering wheel, or uneven tire wear. We inspect the whole steering system, not just the symptom.

Heat & air conditioning

Diagnostics, recharges, compressors, and heater cores. Worth sorting in April rather than in the first week of July.

Battery, starter & charging

A full health check on the battery, alternator, and starter, so a cold January morning doesn't turn into a tow.

Exhaust system

Mufflers, pipes, hangers, and catalytic converters — including the converter problems that keep a car from passing inspection.

Engine repair

Tune-ups, timing components, gaskets, cooling systems, and the bigger jobs. We'll be straight about what a repair is worth on an older car.

Pre-purchase inspection

Bring a used car in before you buy it. An hour on our lift is cheaper than finding out in your own driveway.

Scheduled maintenance

Factory-interval services at 30k, 60k, and 90k — done to spec, without the dealer markup, and without inventing extras.

Fleet & small business

Local contractors, caterers, and delivery vans. We'll keep the whole fleet on a maintenance schedule and get trucks back fast.

Gas, diesel & air

Regular, mid-grade, premium, and diesel from 6:00 am. Fill up on your way in and drop the keys at the same window.

Not sure what's wrong?

A noise, a smell, a shudder, a light you can't place. Describe it however you can — finding the source is our job, not yours.
