“This place was fantastic! I blew a tire on my travel trailer on the Thruway And I was towed to Mahwah To a tire place that was supposed to have what I needed. When we got there, they didn’t and I called at least a dozen local tire places with zero success. I called this place and the guy was so helpful although he did not have the exact tire I needed. He was able to sell me another one that was very similar. I ended up buying two which meant I needed to drive back to my trailer. Install the one tire bring the trailer back to him to install the second tire. The place stayed open an hour later for a complete stranger and saved my family vacation!!!! Had it not been for them my travel Trailer would have been sitting in the middle of a grocery store parking lot certainly overnight. My food would have spoiled and we never would have been able to get back on the road the same evening. Good people still exist! Luckily I live pretty local and will be using them from here on out!”
“The shop is run by Serge — hands down one of the most technically gifted mechanics I’ve met.
I first met him back in the early Audi tuning days, when he was one of the first guys to both turbocharge and supercharge a B6/B7 A4. This was before off-the-shelf everything. Back then, he was building cars properly — custom hardware, custom calibration, tuning on Maestro when the Audi scene still required actual understanding of ME7 logic, load modeling, fueling strategies, and knock control instead of flashing files and hoping for the best.
From there it escalated quickly.
Tesla drivetrain swaps into Audi chassis (including an S5) — full custom wiring, CAN integration, and making it all communicate cleanly with Audi MMI, cluster logic, and factory controls. That alone weeds out 99% of shops.
On the ICE side, he’s built performance engines from the block up, handled motor swaps, full rebuilds, and bespoke turbo systems, and fabricated his own solutions when parts didn’t exist. His TIG welding work on custom turbo manifolds and exhaust setups is the kind of stuff you normally only see in high-end motorsport or boutique race shops.
What really separates Serge, though, is diagnostics.
He has an almost unfair ability to trace electrical faults, drivability issues, and intermittent problems that other shops miss entirely. If ten mechanics couldn’t find it, he usually does — methodically, logically, without guessing. It’s not magic; it’s deep systems-level understanding.
I’ve trusted him with six Audis over more than 12 years — everything from routine maintenance to engine swaps, rebuilds, suspension work, and custom performance setups. Every job was done clean, properly torqued, correctly routed, no shortcuts, no “that’s good enough” mentality.
On top of all that:
Work is clean and documented
Attention to small details most people overlook
Pricing is fair for the level of work
And he’s genuinely enjoyable to deal with — no ego, no bullshit
At this point he’s deep into the supercar world, but the mindset hasn’t changed. Same precision, same standards.
Top-tier mechanic.
Top-tier owner.
The kind of shop you don’t replace once you find it.
P.S. last car he worked on (4.0t twin turbo S6) made 923whp on e40 on a mustang dyno.”
“Hey I want to start using you for my maintenance because of all these stupid protesters. Can you handle 2017 Chevrolet equinox and a 2018 Kia soul? I think I want to swap out all of my spark plugs on the equinox soon so please send me a quote here. Can you program autel TPMs.”
“Courteous and professional service.. I have been a customer for several years and have always appreciated the honest, problem solving advice I get from Bob Crevaux’s Wayne Auto Works. I am a very satisfied customer!”
“I Strongly recommend Gil’s. Expert in diagnosing Lexus problem, then repairing the issue at a fair rate Also, They were very prompt in their response to my need, as I was in Ridgewood visiting from out of town, and their communication was top-notch. You will be glad you chose Gil’s!”
“Hamza is such a humble and friendly owner and his employees are top-tier. Never had a bad experience with them and they’ve helped me out a lot. Highly recommend. Very transparent and honest business. 10/10!!”
“Went for headlight and even though they were full of cars with limited time they listened to me and found a way to service me even though my car required time removing the front fender and I also got my oil change done with full synthetic oil and was able to negotiate a great deal to top it off. I had a mechanic I was loyal to but they motivated me to switch today. I’ll be setvicing all my family’s cars here going forward.”
“I own a 2015 Ranger Rover Evoque and I needed to change my break pads and rooters. I took a chance on these guys and they did a magnificent job! Highly recommend this crew! They earned my business!”
“Jonathan and team are so helpful, so accommodating, and very informative. They explain things really well, their prices are reasonable, and they do great work. When my tire pressure light came on right after the services, Jonathan was happy to check and fill my tires for me. I’ve recommended them to a neighbor as well who was also very pleased with their services. Thanks guys!”
“All-Star staff is very kind, friendly and very knowledgeable. Very helpful. They go the extra mile to make sure that they are providing you with the correct information for your car. they were so nice. My husband was changing the transmission or before escape 2008 and the piece he was buying able to get it so they helped him finding a part. They're also they're very patient about us picking up the car from them. in addition they are extremely patient because my husband asked so many questions kept calling them but they were very very patient and they did a great job. If you need work on your transmission, that's the place to go. Their prices are fair. They were willing to work with you. They are also very knowledgeable and their customer care is Great.”

“Have been going here tires and brakes for years now. (2 x VW's & 2 Chevy's & 2 BMWs) Honest, straight forward and reasonable. Nick and the team have been great and wish them many more years of success. Highly recommend.”
“My 2020 GLS 450 had no heat. The dealership told me they wanted over $8000 to basically replace the entire heating system. Not to mention they had replaced all these parts about a year and one day ago and would not honor their warranty.
Hans was able to get it fixed for under $1000
He completed the work in one day.
They used good parts and were clean and courteous when servicing in my vehicle.
The place is a bit tight, don’t let that scare you. I highly recommend them.”
“I have been bringing my cars to Rich at 3 J's for many years and have never been anything less than fully satisfied. He knows his stuff, provides honest assessments with no pressure, and he's an all around good person to work with. 5 stars all around.”
“Anthony was fantastic to deal with. The dealership wouldn’t help with my Chevy Traverse and Anthony dealt directly with Car Shield to help us out. The work was done quickly and I highly recommend using them.”
“We were recommended to bring our truck here. They repaired our truck within a few days. The service was amazing. The communication between myself and Lewis was spot on! They run a Class A operation and highly recommended !”
“Victor has worked on my family’s cars for years, and he’s someone we trust completely. He’s always honest, which matters more than anything, and he never tries to upsell or push unnecessary work. He’s also the person we can count on in emergencies — he always makes time to help. We do not want to forget Tito...He is a great mechanic. He is always ready to help us..My entire family uses this service..
His prices are fair, his work is solid, and he’s consistently reliable. If you want a mechanic who tells you the truth and stands by his work, Cheo One Auto is it.”
“Always grateful to Jim, Virgil and staff for working with me on a tight schedule to repair my old Baby Benz. Runs fantastic. Sometimes you need the most experienced mechanics, even if it costs a little more. Thanks for keeping the dream alive!”
“I brought them my 2017 Jeep Grand Cherokee to K&K, It was burning oil and misfiring like crazy. I talked to the owner Noah who told me I needed to rebuild the engine and gave me the best local price after quoting a couple other shops. I also purchased the extended warranty for the 3 years. So far after 18 months my truck runs better then new, no more burning oil or misfires. Thank Goodness I didnt trade it in and buy a different truck.”
“Just walked in here to get the auto insurance inspection and the owner (Mr. Bounty) went above and beyond to help me. Will definitely recommend this place for auto repairs and inspection.”
“Excellent customer service very professional and most of all very punctual! I’ve been going to Steve for 4 years due to quality and consistency would highly recommend if in the Garfield area.”
“Vehicle would reverse at idle, but would not accelerate in reverse. If vehicle was parked nose down on a slope, would not back-up due to slippage in transmission. Took it in to R&J.
Todd is a straight-shooter, honest guy, very thorough and collaborative. Transmission is fixed and
I would recommend R&J to anyone with transmission issues.”
“Thorough, experienced and excellent service. They performed 30,000 miles service on my Cadillac. Very pleased with the service, I highly recommend. Thank you Tony.”

“Great and cheap gas station. All is good, but the pump furthest away from the office does not take credit or debit cards, so if that's what you use, don't pull up there.”
“Finding a mechanic you can trust isn't easy, but LM Transmissions has earned my complete confidence. I brought my car in after hearing a strange noise from the engine, expecting a long wait and a hefty bill. Instead, I was greeted warmly, given a clear explanation of what might be wrong, and offered a free diagnostic check.”
“They are People of their Word. The price they tell you is the price you pay. THEY ARE VERY HONEST.
The Shop was closed because of the holiday but i still called and they answered the phone. They were so helpful and helped me during my emeregency. They coordinated an appointment for that same day on the holiday and openned the Shop Just to help me. Thank you so much Enrique and Elena.
FAST and THOROUGH. A truly profesional job!”
“Vincent, Joe and Joe were extremely helpful, efficient and took care of me as soon as possible. Excellent job! Very thorough. Thank you so much! I'll be back and tell my friends about your Excellent, reasonable service.”
“I found Mustafa online and found him to be a great and honest mechanic. If you have a German car, I recommend taking it to him for service/repairs. He fixed my BMW E92 several times. Highly recommend!”
“I had my 2008 Ford F-250 brought in after some shop screwed up my front end at a place in Ny state. Total Performance is the best shop in the AREA hands down , the guys fixed my front end, rebuilt my rear due to it was howling, starter replaced , and now I’m bringing my truck back for more work to be done cause Ford sucks when it comes to rotting. My truck is lifted with 37x12.50r17 2 door supercab with an 8 foot bed. I couldn’t be more happy with the work they have done all the times replacing those parts that I listed, and the staff are amazing and I can’t forget the owner and his lovely wife that helped me with my quotes. If your looking for a Professional 4x4 Specialist’s either Diesel or Gas or even a car I would highly recommend Total Performance In Mahwah. Thanks Total Performance for saving my truck !!”
