OUR SERVICES

PHIL MCADAM HAS SPENT DECADES EARNING PLAISTOW’S TRUST — WITH HONEST ADVICE, FAIR PRICING, AND SERVICE THAT PUTS PEOPLE FIRST.

Auto Repair & Maintenance

ATI Automotive has been proudly owned and operated by Phil McAdam for nearly three decades. Phil began working on vehicles in 1990 and opened his Plaistow shop in 1995 — built on the belief that customers deserve honest guidance, fair pricing, and high-quality repairs they can rely on.

From quick oil changes and fluid checks to advanced diagnostics, suspension, brakes, and engine repairs, Phil and his experienced team are here to keep your vehicle safe and running strong — without the upsells and headaches you’ll find at big dealer service departments.

At ATI, you get straight answers, skilled workmanship, and personal attention from a team that cares about your safety and your wallet.

Honest work. Fair pricing. Local roots.
That’s the ATI way.

Quality Used Vehicles

When it’s time for your next car, you shouldn’t have to stress about quality or hidden problems. Every used vehicle on our lot goes through a thorough inspection, and we only offer cars we’d be comfortable putting our own families in.

Phil hand-selects each vehicle and makes sure it’s road-ready, well-maintained, and affordably priced — often below book value. Many also receive NH Oil Undercoat protection to help them withstand New England weather for years to come.

With ATI Automotive, you’ll find dependable, budget-friendly vehicles backed by a local shop that stands behind what it sells.

Reliable vehicles. Trusted dealer. One stop for everything.

WHAT OUR CUSTOMERS
ARE SAYING ABOUT US

Tina T
Phil, Brian, Brian Jr and Anna are terrific! They are always knowledgeable and willing to answer all questions I have. They do great work and are very fair. Great people great place.
Suzan H
Phill is amazing. He is honest. He takes the time to actually show me what is wrong on my car. Being a woman and not knowing about cars you can get taken advantage of. Not here. I’ve had my husband tell me what’s wrong with my car but have no time to fix it so I took it to ATI and they told me the exact problem no BS or extra cost just the truth. I trust Phill so much I have my two girl go to him. Best mechanic ever.
Brian M
Awesome people. Phil is the best. Always fair always honest and always willing to bend over backwards for me. If you are leery of mechanics this is the place you should be going. No one in the area is as honest as Phil. Sometimes he's busy but it's worth the wait.
Tiffani M
Just got an inspection sticker, but both the people I spoke to were nice and I was in and out in less than 15 minutes. Would definitely go back for other work.
Jesse E
My boss referred me to these guys. Phil is an amazing mechanic. He is honest, and will shop around for the lowest prices for parts. Best shop in NH hands down.
Will
Phenomenal service and walked me through the process of owning my first car. The owner Phil and his wife are amazing people, I highly recommend this place.
