“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.”
“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!”
“Brought my car in for oil change. It was the first time I used Pry Auto. They did a complete fluid check and made sure the car was in good condition before leaving their site. They are friendly & address any questions you may have.”
“These guys are awesome and have earned my trust. They have a ton of great reviews on Google for a reason. My VW was having issues with the heater in the middle of the winter after just moving across the country. They didn't charge me a fee for inspecting it which was really nice. They said they would only charge a fee for diagnosing the problem if it required a lot of labor like pulling the dash out which was totally fair. They gave me a lot of information that really helped me weigh out my options. They told me I still had full coolant levels so the first thing they would do to try to fix the heat in my car is to flush the coolant, flush the heater core. They quoted me $630 total for the job which I thought was fair. He warned me that may or may not fix the problem and if it doesn't then it's very likely I will need a new heater core. The tech emphasized I should really consider if I want to start dumping money into my car as there are other issues that are costly and it may make more sense to eventually just get a new car rather than pouring money into trying to get all these issues fixed. The other issues I had included an intermittent flashing power steering light which the tech told me is an indication my electric power steering rack is going bad and may need to be totally replaced which would cost more than my car is worth. It would not make financial sense to replace it. Additionally, I have a check engine light on (emission related) and would not be able to register my car. These guys have been really been transparent with me and didnt try to take advantage. They provided me with a lot of information and advice to help me make informed decisions. Ultimately I took the techs advice and chose not to invest in repairs and have decided to eventually replace my car. When the time comes of needing a service or any kind of repairs - this is the only shop I will be bringing my car to. They've earned our trust and business! Also I don't know if they had anything to do with this or not, but I swear since leaving their shop my heat has actually been working better!! I managed to get through my first winter in jersey Now time to look for a new car. Thank you gentlemen - I really appreciate you guys for all your time, advice, and help!”
“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.”
“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!”
“Josh and everyone I’ve met at SK auto have always been honest and helpful to everyone in my family. We don’t use anyone else and cannot recommend them enough.”

“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.”
“High mountain is my go to local mechanic. Mario and Joe are just overall incredible stand up guys. They always take care of me and all my vehicle troubles. You guys are the best!”
“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!”
“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.”
“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 !!”
“Let's face it, we all live a very busy life whether it is with work, kids, school, etc. and when something goes wrong with your vehicle especially with transmissions the first thing that crosses your mind is, time & money. Not only was Lorenzo very professional and very thorough when explaining what the issue was, but also he was done fixing my truck's transmission in only three days and to top it off the price was very reasonable. When it comes to transmissions, I highly recommend this place to all my Northern New Jersey folks, because of how effective and reliable they are and for the fast turn around. My truck runs very smoothly now and I'm back to my everyday routine. Thanks Lorenzo ??”
“I recently had the pleasure of visiting Glen Toyota for some service needs, and I must say, the experience exceeded my expectations. From the moment I walked in, I was greeted with warmth and professionalism. However, what truly made my visit remarkable was the outstanding assistance I received from Freddy.
Freddy went above and beyond to ensure that my service needs were addressed promptly and effectively. His knowledge about the intricacies of the service process was impressive, and he patiently answered all of my questions, putting my mind at ease. What stood out the most was his genuine dedication to customer satisfaction. He took the time to understand my concerns and provided personalized recommendations that suited my needs perfectly.
Moreover, Freddy's friendly demeanor and positive attitude made the entire experience enjoyable. Despite the busy environment, he remained attentive and focused on delivering top-notch service. It's evident that he takes great pride in his work and genuinely cares about the well-being of the customers.
Overall, my experience at Glen Toyota service department was nothing short of exceptional, and it was largely thanks to Freddy's outstanding service. He is a true asset to the team and exemplifies the values of professionalism and customer-centricity. I highly recommend Glen Toyota to anyone in need of automotive service, and I can assure you that with employees like Freddy, you'll be in good hands.”

“Been using the same mechanic for over 3.5 years. 75,000 miles later, car never gives me problems. Anything he’s installed has not failed on me due to mechanic installation. Prices are extremely fair. Solid work, no bones about it.”
“I ordered part thru Toyota Website for my 2021 Venza, they offer the best prices among other Toyota dealers. Paul from parts also called me to update me about my order and status so he makes sure i am purchasing the right part and its fit to my vehicle. They care about their customers. Liked it. Definitely recommend them!”
“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!”
