Kos Motorcars

This is where you should come for ALL THINGS CAR RELATED. They are the experts you were always hoping to find. I have been their customer for 6 years and I don’t dare to look elsewhere. They are the pros, they are the doctors, they are the Michael_Angelo’s of car repairs. Over time I have seen people fleeing specialty dealer shops, coming to KOS and never looking back. They are the mechanics you never leave.

10 Year Customer of Kos Motorcars In Montclair NJ
Pros: Great hourly Rates, Over 20 Years Experience with German Cars
Cons: Lack of TV in waiting room area, Lack of A/​C in waiting area
On June 20^th I had visited in with a serious problem with my engine on my 2002 Mercedes s500. I was terrified the car was in horrible unsafe driving condition and was overheating. After about 20 min and a quick look at my car on the lift the owner (Walter) had pin pointed my problem.
The bottom line I needed a fan assembly and motor mounts. I was fairly priced and offered a discount as always on the parts. These guys always get me OEM parts for a third of the price. I am a big fan of using quality products on my car. Then fan assembly listed for $ 1100 dollars and they sold it to me for $ 600, AMAZING! The engine mounts list for $ 154 each they gave them to me for $ 55 !
Overall, my experience was positive as always. Its been 10 years and never had an issue maybe once when it was 95 degrees in the waiting area, but that never deterred me from the quality of work I know I will receive here.
Update: Most recent visit was a life saver. My cars belts were about to snap, tech noticed and was replaced fairly quickly at a reasonable price.

I have been a customer for about 4 years.
Over Walter is a nice guy, but I’m afraid to admit it, quality of work is degrading. KOS Motorcars is a great place to get oil changes and maybe change your brake pads, but that’s about it. Once they open up your car, its problem after problem.
I had to go for the same 3 issues with my car 3 times each (9 times), and they are still the same as it was when I came in the 1^st time.
Granted, he didn’t change me the other times I came in, only the 1^st time ~ but even though, the initial issue persists.
I still have all the same problems, and/​or worse from they «short cuts» the mechanics made. (ex. bending my sub-​frame to fit my down pipe in ~ told me it was OEM, but apparently it wasn’t). Also, seems like he dropped my CAT and destroyed my O2 sensor (codes came up that were never there) — still have those codes.
Snapping when I turn, he replaced both front axels, it still snapped, then after a few days, the CV boot ripped, he replaced it under «warranty» but the snapping still persists.
Timing belt, belt is on right, but alternator squeaks now, had to go back because the new thermostat he put it was stuck open. after that, coolant broke down my coolant flange (assuming distilled water wasn’t used ~ no big deal, I replaced it myself but had to buy new coolant too and do a flush) Alternator still squeaks.
Basically, just take your $ 3000 to the dealer, get it fixed ONCE the right way
