Advice: Buying a 2021 C63 AMG S
I called the Chevy dealer in Michigan that has the 4k one. They bought the car at an auction for a Michigan football player who was just drafted to the Chicago Bears. He then rejected the car, so the Chevy dealer is stuck with it. I got the service record from a friend who works at another MB dealer - it has only seen an MB dealer once in 4 years and has never had a full service A or B. That is a red flag. Dealer also won’t come down on price, so I think it’s a pass. Here is the link again to that car

My last car was a 2020 C43 (had it for three years). I loved that car and likely should have bought that. Live and learn. I need a car again and figured I might as well go for the 63! That said, it will be a new experience in terms of power and the RWD.
I have a slight concern on how loud the interior will be from the exhaust but it sounds like it shouldn’t be bad when in Comfort mode. I have some flashbacks to the 90s of idiot friends and their modded out ricers and how loud they were inside the car. I assume that won’t be an issue here!

As for exhaust note, that is the beauty thing of AMGs, dual personality. Gentleman in a suit with a flip of a button. The facelift also have the very nice 9-stage traffic control that forum member superswiss goes in depth on explaining. Let me see if I can find his thread.
C 43 is a car that you want when you find the C 300 too slow. C 63 S on the other hand is for those who are serious about performance and fun.
Keep in mind, I said this despite myself still having a C 43. I live in Canada and back then (2017) when I purchased this new, I needed (or felt more confident with) 4MATIC, as it snows like 3 seasons here and I don't like the idea of garage queens : )

Sorry I mean traction control, maybe when you drive pass traffic, they stop to see what just passed them, so basically it does control traffic/clear it, they give their way





haha. I basically plan to drive this car rather conservatively relative to others on here. I don’t plan to be doing skids. I’ll definitely need a tutorial - in layman’s - terms for the different modes.
What is the “elderly mom” mode? Is that just comfort? My mom is coming with me and we are working a road trip out of it. I also plan to store the car with her - and away from garages in NYC - so the car doesn’t get damaged
pick up is scheduled for next Wednesday!

There's a whole slew of adjustability in this car. It's sort of Dr. Jekyll and Mr. Hyde. Yes, the mom mode is Comfort. There's one more mode below Comfort in the 2019+ models called Slippery. You guessed it for what that is. It reduces engine torque and makes the throttle less sensitive, so you are less likely to spin the wheels when the roads get slippery. But driving this car around only in Comfort mode would be sad. You'll be missing out on what a C63 is about. I highly recommend you attend one of the AMG Experience events (link below). When buying a brand new 63 it includes a complementary AMG Experience day. It's a great experience and you really learn what these cars are capable of and you learn the limits in a safe environment. Well worth it even if you have to pay for the day since you are buying used.
It is somewhat sad that many people buy these cars and then do mundane commuter traffic type driving. These cars are so much more. If that's all the kind of driving you plan to do, then a 63 is not worth it over a 43. Yes, you get the V8 rumble, but you also get a stiffer ride and more NVH, for essentially nothing in return unless you start opening this thing up in the sport and race modes.

nice, Wednesday is not a long time from now at all! Don't let it keep you awake at night though, time goes slower that way (personal experience).

I have my 2019 C63s coupe since new and swap out my summer tires to winter tires usually early/mid December then back to summer performance tires in march. I keep the same rims. AMG Forged Cross Spoke wheels in Black. Staggered F 255/35/19 and R 285/30/20.
I never had any issues with some moderate snow and ice but concerning is using the car in freezing cold weather with summer tires.
Here are the new Michelin Pilot Alpin 5 snow tires I installed this this year. They were much better, I felt than the Pirelli Sottozero 3. A lot less bulky looking and smoother during driving conditions. As you can see by photos.
Currenty I use the car 2-3 times a week.
* If you plan to purchase a Winter tire set up do so by ordering beginning of October as they do sell out quickly esp with my set up.
Ordered from Tire Rack about $1,900.00.
Good luck with the car.




If OP has never even driven a 63, I would highly recommend to first go for a test drive. His elderly mom may not enjoy it if the roads are anything but smooth. NY is not known for good roads, just saying. The transmission is also at a different level given that it uses a clutch instead of a torque converter and requires thought with the throttle input to keep things smooth.

Sorry for all the basic questions here

I probably sound like a wimp because I want to get a good feel and build confidence with how to operate the machine.
The amg driving class is a great idea. I will look into it - perhaps a good vacation idea

1) drivers assistance package - an absolute must have imo. I live in LA and rarely use it for its autonomous features, but when I do it’s a huge pleasure and convenience. The value I see every time I drive are the safety features that prevent the car from getting into accidents (your blunder or not) which comes with the package. Besides its utility for the driver, the package significantly modernizes the car and resale value is that much better. When I was shopping cars without the package and brought it up, every salesman’s face showed weakness. They know people want the package and you definitely can leverage concessions if the car is without it. Basically a loaded c63 is future proof.
2) don’t fall in love too much with CPO status. Dealers have to pay Mercedes thousands to CPO the car. Basically CPO means if a car has a clean history and is not cosmetically beat, the dealer will take the risk and make the investment to CPO the car so they can sell it for much more. They also get the returns on when you do come in for warranty work, they can sell you on wear and tear items so they create a higher LTV from you as a customer. Mercedes takes the risk of paying for warranty repairs, but that is offset on the money they made from the dealer as well as the event that nothing goes wrong. Though I’ll say the marketing behind the CPO is strong. Whether it’s superficial or not, it effectively creates “peace of mind” which alone can make a buyer buy despite any other shortcoming, like a missing option, and especially on cars like amgs where forums are littered with fear and problems lol.
3) known concerns - law of attraction. Talk about and look for problems and you’ll certainly find them. Enjoy your car and life in good health my brother!
