Buying Advice

Hi, I'm hoping to buy a '17 or '18 C 43. I'm concerned after seeing some posts about blown engines that had tunes on them. If I dont buy certified pre owned, is there a way to tell if a car had a tune on it at some point? Should I only consider cpo? Is this something I shouldn't be too worried about? Thanks.

Buying used performance vehicles is best if you can bring a mechanic with you. No matter what the original owner of the vehicle says, the car has probably been driven hard. Why are you looking to buy a C43? I doubt it's just to never floor it and stay under 100mph

I completely agree with the above comment. I think the peace of mind that comes with a CPO vehicle is worth the extra cost on a car like the c43.

You know, most used car dealer trades in, they hardly do any work or even give it a good inspection and stamp their CPO tag on it.

OP is worried about tunes and most piggyback tune don't even register on their inspections once removed and required thorough look at the ECU. Even then it's hard to tell. Now if OP bought a C43 that was tuned and removed and within 2 years of CPO warranty, engine blew up, do you think benz will go extensive length to prove there was a tune? I think they will and if they find there was a tune, I think they will blame the current owner of turning the car and removing it to have their car warrantied.

Yes, I am aware of that. For the CPO warranty that comes with the car, it mitigates the concern of failure within a reasonable length of time after purchase. Aside from that, everything else in your post is conjecture based upon a hypothetical - but that said, I do not disagree.

In Canada, the price was around 2000 more at the Merc dealer but you get the star certified or whatever they call their CPO warranty. I decided to go with Merc CPO only because when I considered how much I was spending, the $2000 extra to gain warranty was well worth it. I also managed to get free service for 2 years. I got that because they lowballed me on my trade in (which I expected them too) so I used that to my advantage to get some "free" stuff. They advised the car came with its original warranty up to December (as mine is a 2018) and as that expires my CPO warranty will kick in and I have an option to go there before it kicks in to pay and upgrade it to bumper-to-bumper just like a new lease which I will do most likely.

Hope this helps you and DO NOT BUY ONE WITH OUT THE PE. You will regret it. I was looking for 2 months before I found the one for me. It is really stupid that it was ever an option to be added. Easiest way to tell is to look for the AMG logo on the bottom of the steering wheel. The car is dull without it. (PE is part of the AMG Driver's Package).

Speaking of the Driver's Package it comes with the 19 inch wheels so if you notice that it has the regular 18 inch 5 spoke star shape wheels, it doesn't have PE.
Edit: At least true for the Canadian market, other markets it depends on the red stitching on the dashboard vs regular stitching. I heard that Germany you can option the performance exhaust separately while not having the logo on the bottom of the steering wheel with regular 18 inch wheels.

I guess the PE sound really depends on your personal taste, I heard some C43's with the PE at my local track and the sound isn't for me. It is loud and raspy, but no depth to the sound, very hollow sounding in my opinion. Maybe it sounds better in the car? The standard "Sport" exhaust sounds fine to me. If it was a V8 C63 or something it would be a different story.

There is pumped-in audio so it does sound slightly different inside.

yeah I am in the same boat. the only reason I would get the PE is to make it more attractive when I want to sell it because it seems to be pretty popular but the sound itself is just way too loud and tacky. Standard exhaust for V6 is properly tuned.

V8 however is a different story.

I also prefer the Sport Exhaust to the PE. The PE has no bass and is just mid to high frequencies, and sounds a bit cheesy with the pops and bangs, Sport Exhaust sounds more sophisticated and classier in my opinion. Among my group of C43 owner friends, the ones with Sport Exhaust seem to be smoother in performance, slightly more powerful.

I disagree. I've been to many meets with other C43 and the PE sounds more open to me. The Sport Exhaust sounds muffled and muted and I don't like that one bit. At below 4k rpm and at idle, the PE also sounds deeper and open as well. I don't think either exhaust option really makes a difference in terms of noticeable performance anyhow.

Hmmm, speaking of V8, I wasn't able to find a video comparing the standard sport exhaust vs the AMG Performance exhaust on the C63/S. Are they noticeable different in sound?

pretty sure PE is standard on all AMG V8, aka the only option. what I meant was V8 low pitch rumble through PE sounds great but V6...? meh. I know I am in minority but for a V6 sport exhaust without valves is sufficient in my opinion. V6 is not a true AMG engine anyways.

Correct. I was shopping for a C43 some months back (Australia) and came across one that had the performance exhaust, but didn't have the Drivers package (sport seats and AMG logo on steering wheel. it did look like a special order, as it had white leather interior.

I have noticed the Australian delivered C43's come optioned to the hilt. it seems like the British and US versions from what I have seen come bare bones, then it's up to the buyer to option up. I think of the 4-45 cars i saw advertised, only one didn't have the PE option

In Canada at least, the performance exhaust for pfl C63 and C63s were optional. The standard was the sport exhaust. Facelift C63/S were standard however
