Questions from a noob
1. I want to buy a used C63 AMG (W204). For someone who barely know anything about cars, is this a bad idea?
2. Does Mercedes still sell engine parts for this car? What about 5-10 years from now?
3. If I replace the m156 engine with a remanufactured engine will it be similar to owning a new car? Does Mercedes even sell a remanufactured m156? How practical/cost effective is this? Maybe this should be done later when I start to run into engine issues? But will they stop selling the engine in the future?
4. I've done some research on how to inspect used cars but apart from generic advice is there anything specific I should look for when buying this car?
Thank you! Any response will be greatly appreciated.

Do yourself a favor and start researching

1. Yes it’s a bad idea, unfortunately. The C63 has a 6.2 V8 engine. Probably the most powerful engine you’ll ever drive. I mean, it’s no joke. For a new driver who hasn’t driven anything before, except the car you learned in, you’ll be asking for trouble.
This car is maybe 10 times more powerful than the standard cars people learn to drive in (UK). You’ll have no experience in how to control that power. The car is also pretty big in size for a first timer, especially in terms of parking.
Plus insurance. I doubt any insurer in the U.K. will insure you on this car as a young first time driver with no experience. If they did, it would cost thousands a year. I’m in my 40’s with lots of experience and my insurance is £700 a year on this car. My old insurer wouldn’t touch the car. They wanted nothing to do with a C63. I had to move insurance companies.
2. Yes Mercedes still sell parts for the car and should do for the next 5 years. The w204 was still being produced up to almost 5 years ago, so parts are readily available. Be aware that this is an AMG so some parts will be expensive.
3. Not practical or realistic. Huge, huge expense. Thousands of dollars/pounds. $/£. The engines aren’t readily available as complete units to drop into an existing car. There’s gonna be much more experienced people here than me on this topic.
4. As with all cars go for a car with as little mileage as possible. If you can afford it go for a 125 edition or even better, a 507 edition. Try and get a facelift version regardless (mid 2011 and onwards).
Due to the nature of this car, 6.2 V8 that sounds wonderful and goes very, very fast, a lot (maybe all) of these cars have been driven pretty hard by previous owners.
Beware that this car isn’t the best for fuel efficiency and runs only on Super Unleaded premium fuel. You need to factor that into your running costs. 17-22 mpg is the norm for this car.

Same as me, I’m looking to keep mine for a long time but I’m not at all worried about the availability of parts.

The big issue was the Yellow Check Engine Light came on when I was driving it home after first buying up the car. The car wasn’t smooth at very low speeds and idling, but normal speeds were fine. I had it looked at and had a broken PCV valve. A fairly common fault. Cost me £200 GBP to fix.
The second was the air conditioning. It wasn’t cold on the passenger side. Re-gas and air conditioning motor recalibration fixed that. £100 GBP.
That’s it so far with my car. But only today, the parking brake was difficult to release. Not sure why that was.
Oh, there was also an intermittent noise the car made when I got it that sounded like a fan-belt noise in any other car. But after getting the PCV valve fixed that noise has gone away.
I guess some teething problems are expected when you buy a 9 year old car with 83,000 miles on the clock.
The Best of Mercedes & AMG




I have logged over 300 hours of performance racing time in dry and wet weather at over 150mph speeds.
This happened at 37 mph bc of how much torque this car has

I am 50 years old, have been (legally) driving for 34 of them, doing track events for the last 20, I hold a racing licence and have been racing in the dry, wet and on ice for the last 7, and have been instructing for the last 4. None of us here that are telling you that a C63 is not a good car for you to drive when you're a new driver are jealous or want you to not have a good time. We are telling you this because we want you to live long enough so that you can continue to enjoy the feeling of stomping on the pedal for many more years to come. You really don't need to worry about engine longevity or parts availability as chances are overwhelmingly that you're going to wreck it way before you experience any mechanical issues.

That said, accidents do happen. Anybody can handle a c63 and you shouldn't be afraid of the car because it is a drivers car. You just have to respect it and know when to and when not to give it hell. If you treat it well it will treat you well and vice versa. You just have to be real with yourself in the decision making process of whether or not to get one. It's why I don't have a motorcycle haha

I'd love to drive one that has been put on a diet and well sorted for track use like yours or BLKROKT's... that would be a blast!

I am still tuning the suspension but it's for sure when over driving a corner. TMP doesn't really like having the pizza cutters up front even with the car under 3400lbs.
Getting used to the braking threshold as well so blowing a corner entry because ABS makes an appearance was a frequent laugh. I wasn't able to throttle correct with TC in sport in those situations.
I've never had a track car with TC before. Curious how much affect the weight cut and suspension has on the TC algorithms.

A VW Golf R is another fast and very capable car (also AWD and FWD biased) that would be just as much fun to drive, and would likely cost even less money.
If you actually want a RWD car that will kick out the rear end when you get on the throttle and has even better handling, a BMW 135i is next to impossible to beat.
The CLA & GLA have been around for 5 years now, and the BMW 135i and Golf R for over 10. All of them had an initial purchase price about 2/3rds of that of a C63, so you could presumably get any one of these that will be in better shape than a C63 for the same amount of money. ALL OF THEM will put a much bigger smile on your face when you step on the throttle that what you are getting from the C200, and despite the fact that they go like a bat out of hell, none of them will try to kill you when you make a small mistake. The BMW is a RWD and the back can and will step out if you're not careful, but at least it won't shove you in the wall at the same rate that a C63 would so you actually might have a chance to gather it back up.
This weekend I took it out for a more spirited drive and enjoyed it in Sport mode (still with ESP on). When I was coming back home, back on Comfort mode, I stabbed the throttle a bit too hard on a roundabout and the rear end let go a bit. It came back mostly on its own (thank ESP) + a minor correction.
It was exhilarating and fun as I don't have any previous RWD experience, but also a reminder that this thing needs to be treated with respect even in Comfort mode with ESP on.
I'm 32 now and I wouldn't hand 20 year old me the keys to this car.
