Cool Difference between 2020 and 2017 c43

Hello everyone,

I was interested in a 2020 c43.
The private seller sold it to a dealership who then added 2900 to his (the private seller's) previous asking price of 41 600$ (And I am 100% sold it at about 2000 to 2600 under his asking price).

I am now looking at a 2017 c43.

The body body styling is worse on the 2017, but for the price difference (10k), i can live with that.

My question is:

For those who have experience with pre and post-facelift, what are the significant differences in terms of driving?

Thanks

If you're into tuning 2019+ models will have the CPC locked up. Big $$ to get it unlocked.
I drive a 2020 fully loaded with red seats. Got mine 53k miles for 38K out the door (2025 May) and I love the hell out of it.
Get rid of the stock run flats and it drives great. The 2019+ models with the digital dash and leather seats... Chefs kiss

38k USD?
Is that in line with market value in the US?

I'd say used 30-40k USD is the range based on miles, spec, body condition, and history. Mine was fully loaded, w/ track pack, garage kept + summer only, and the paint looked new. The 2018 M3 I was comparing at couldn't come close to features.
I took a video of when I was looking at mine. I still feel giddy when I watch it :P

It looks really nice.

The 2020 that I was looking at is similar (mileage specs, and condition) but blue paint and 2 amg sport seats in the front instead of leather,
How much was your car itself, without title tax and license?
I am not willing to go over the equivalent of 34k usd OTD. Dealer wants 37. No deal for me.

It was posted for 38k on the site and my budget was under 40. I told them to make it 38k out the door and they did "because they liked me". Also, they took it to MB for an oil change.
Good luck on your car hunt!

So there are really 3 versions. There is the 2016 only C450, basically the same car as the 2017-18, but it gets the 7spd auto rather than the 9spd. The 2017 and 18 C43s get the 9spd auto. All 3 of these model years make ~360hp. In 2019 there was another facelift. If I recall correctly the facelift got a slightly different bumper, headlights, tail lights, and slightly more power up to ~390hp. That power bump is basically just a different ecu tune though, as far as I'm aware there are basically no mechanical differences between the 2017/18 and 2019+ cars. The 2019+ cars also got different head units with a larger screen and carplay. The 2019+ cars also have an extra particulate filter in the exhaust I believe, so the slightly older cars generally sound better, or so people say. I'd say to just try and find the best deal, maybe also try and find a car with the AMG PE exhaust option. The cars can come with distronic and I think also a heads up display, but the tech might not be a high priority for you, and you can retrofit carplay pretty easily. Somebody else said this, but just generally as you go newer the tech gets more locked down, so mods get harder and more expensive to do.
