Mr. Patti is an amazingly smart technician and teacher. He was my auto shop professor in high school and has always been a trustworthy resource for me when I run into car issues many years later. I no longer live in Massachusetts, but I visit him every time I come home to say hello. A very valuable person to me in car knowledge and an extremely trustworthy person. I’d never take my car anywhere else if I still lived there.

Nice bunch of friendly people. A good neighborhood shop and a NAPA AutoCare Center. (My car had a new AC compressor and relay.)

Lou and his team are the best around for quality repair, affordability, and honesty. Ive left my vehicle with them several times and each time the issues were fixed with quick turnaround. Never had a complaint and neither have my friends/family who also get helped here.

This is the type of business that truly cares about its clients. Theyll take the time to show you what is going on with your car and give you a fair price for the fix.

This is a shop that you can trust has the experience and knowledge to understand the issue(s), give you the proper recommendation(s), give you a fair price, deliver on-time and do it right. Dont hesitate on calling Lou and making an appointment to fix your car. Heres some examples of the work Lou has done for me over the years:1. Bought in an 8 year old Chrysler Town and Country to examine and get it ready for my nephews 4-month cross-country trip to explore the USA. He replaced the tires, brakes and heat-A/C blower (and threw in an oil change) and pronounced everything else as safe for the trip. The car successfully made the trip without incident.2. Towed my Kia Sorento to him to replace a broken high-pressure power steering line and flushed the system. While there he noticed there was a coolant leak which he easily fixed by replacing corroded clamps.3. Expertly custom-Installed a trailer hitch and wiring on a new Kia Niro EV. Where others on YouTube removed a rear protective cover, he cut and refit the unit perfectly.Call him to make an appointment, drop the car off in the morning and it will be ready when he promises.

I would highly recommend, Lou is our go to mechanic, always reasonable and quick turn around

Great shop. 10/10 would recommend. Louie, great guy. Steve, top notch 👌

Lou is great. Been coming here for years. He always has a few options on what to do, and the work is solid.

Apologies for prior negative review upon further review this is a good business

I was having a tricky issue with one one of the lights of my dashboard. Lou spent quite some time investigating it. He fixed it at a very reasonable price. Reliable mechanic and great customer service.

Old school shop, right down to the pics of SS Chevelles and 440 Road Runners on the wall. Lou’s been down every road, just a straight up guy making an honest living. Lots of cars out front, you’ll wait your turn. He’s on a bus line to Alewife, so just leave it and chill. No BS.

I have been going to Grey Patti for at least 20 years. Lou is extremely reliable, does not recommend more than what needs to be done, goes out of his way for his customers, does not overcharge and does great work. He is very busy, which in my book means he is in demand and therefore worth the wait. I read the negative review written about him. Though he didnt find anything wrong with the guys car, he still spent time checking it out and should be paid for that time. I cant recommend him highly enough.

Good old-fashioned mechanical repairs for my Mitsubishi Eclipse. I have used these guys for internal engine work (timing belt replacement), engine accessory work (water pump, belts, motor mount), and a perplexing fuel system check engine issue (replace rusty [no longer airtight] filler mechanism).In all cases they did good work in a timely manner. They are not fancy, you wont get loaner wheels or upholstered waiting room; but your car will get fixed.I have not shopped for price comparison since their prices were not excessive and did beat New Street on the one item both shops saw.As with any good shop in a populated area, you may have to wait for your turn in their shop.

Honest and fast. Will go back again and again.

Great service. Had a noise that I was concerned about. Checked it out for free.

I really feel like I can trust Lou. That is so important to me in a mechanic! I wont go anywhere else.

On time, done right, good price no hassle

Knowledgeable, capable, courteous, did the job well, couldnt me more satisfied!! Way to go Lou.

Excellent, honest repairmen. Wouldnt go anywhere else.

First of all sorry for my broken english but i want to share my experiance with this guys. I brought my wifes old 2001 ford focus because i had handbreak lights on all the time. I just asked him how much would it cost to change break pads and he told me about 200 USD. I had no idea about price because i was new in country. When I call two more mechanics from Arlington, MA they told me 90 and 100 dollars with same brand of pads and same car and same job. It was actually my second bad experiance with this place. Last summer when I bring my Buick Century 2000 because of some licking on my parking lot. He took the car keep it there for 5 hours and He finally told me that there wasnt any problem It was just airconditioner water I was happy with than until I hear he would charge me 50 dollars for this. He didnt put any new part, he didnt fix anything he probably checked some stuff in there and it was the value.Edit: When I go back to get my ford focus he told me to pay 60 USD to say Your car is fine!!! (without change anypart or fix something). I told him that I dont want to pay that much for just checking and he started to fight (not phsicly with words) with me and finally kicked me out of his place. I wanted to pay some money for his workers because they did all job and i didnt wanted to get it for free but honestly I didnt have any chance. I was not able to stay there because high tantion.I am hopping to find the mechanicer who worked with my car and spend some time (not owner the place) out side on street and give him a 30 - 40 dollars tip.So this is the story of me with this place. I just wanted to share.He might be a good mechanicer when you need but I felt like he wasnt honest with me and he always wants to charge as much as possible money from me. I would never ever go same place again and I would never tell people to go there. I live in America for 7 months now and first time I felt that way in this country.

Great mechanics, fair prices

Very friendly! Had an urgent situation and they helped right away!

Super satisfied

Great Service
