Yes.Is it possible to post a video on here of this car running. I've posted it elsewhere and a number of people have said it sounds rough as hell. I figured it was just because of the surroundings of the showroom, but I'd like some more opinions if possible.
Thank you.Yes.
Save vid to youtube and then post url link here.

Thank you👍🏼Agree that it sounds odd, but perhaps due to the echo in the showroom as not as noticeable outside.
If it is an issue, possibly sticky exhaust flaps.
@Col is more familiar with this model and I believe is also familiar with the exhaust flaps issue.
@Carspito55 is also familiar with that model.
I recorded it on my Samsung mobile.@Daveg2812 Here is a link to mine (6) Cold Start AMG SLK55 - YouTube
From what I heard from yours the sound did improve when the car left the showroom. I would go back and get them to start the car outside of the showroom preferably from cold. What device did you record the sound on?
Thanks Col,Hi @Daveg2812, it’s a small world. I was the one on the Facebook group that advised you to check the flap motors after the negative comments. I wouldn’t let it stop you making the purchase in any event even if they were faulty. It’s a simple fix (if the parts are available and not on back order) and I myself found that my own car had a duff flap motor when I bought it. I was covered by an MB approved used warranty so it was sorted foc. In your case it might a point of negotiation or if they won’t drop the price insist that they cover the cost of repair.
A few simple checks will determine the status of the flaps on the car.
1. Do a visual check by shining a torch down the inboard pipes. See if they are present and if they are in the same position with the ignition off.
2.With ignition on (engine off) you should witness both flaps open and close. If one or both don’t move you have a problem.
3. Check the cable is plugged into the motor on each side and they are not damaged.
Another thing to note is that all M152 engines have a slightly rough idle anyway. It is a characteristic of the engine. Sound doesn’t always accurately come over in videos, in fact they really do not do the car any justice whatsoever.
If you need anymore pointers give me a shout.
Looks like a tidy car, so good luck and I hope it all works out for you.

There‘s no way I’d buy a car that’s making that noise in the dealership. It could be an easy fix as Col says, but I’d be insisting on the garage fixing it before collection. The car has recently been serviced but the dealer should be fixing that before even advertising it.Thank you.
Below is the link to the video of what some have said is a very rough sounding 55 AMG that I've just put a deposit on. It's done 34,000 miles, has a comprehensive service history including transmission service at 26,000 miles and the last service was 500 miles ago. I'm certainly not an expert on this model and it sounds to me pretty much as I expected. I'd appreciate some comments from those who know better and any pointers as to what the issue might be, if there is one.
Thanks

Does this sound right?

So many conflicting opinions. As I've said, I'll get the garage to check it out.There‘s no way I’d buy a car that’s making that noise in the dealership. It could be an easy fix as Col says, but I’d be insisting on the garage fixing it before collection. The car has recently been serviced but the dealer should be fixing that before even advertising it.
Its a nice car and you could luck out with a straight forward fix, but it’s a risk in my view and there are a lot of cars about at that price point.
Just my view.
No, not yet. Going in tomorrow. Might come home with it but not sure yet. Will certainly happen this week though. Sold my 350 though and that's going tomorrow I think, so hopefully won't be without wheels for too long!Well @Daveg2812 it's the 1st. Have you finalized this deal? 🤞
