"Best" Mercedes to own

Would I recommend this vehicle, no. I was told that this was the "best" vehicle to own in the Mercedes-Benz line up and that has definitely failed to be accurate. After about 8 months of owning the vehicle, I stated to have engine turn over issues. I would click the start/stop button and it would sometimes turn over and sometimes fail to do so. I was told that by service advisors and the service manager that nothing could be done if it did not happen in the dealership service center or in front of them. Although I had video footage of what the vehicle was doing. At one point while making a left hand turn on a flashing yellow, the accelerator failed mid turn, causing me to almost cause an accident while making the turn in front of an on coming vehicle at 5 mph. Pedestrians thought that I was doing it on purpose. I pulled over, turned the vehicle off and then back on. The accelerator worked fine after that. I took it back in and was told that there was no recalls or complaints, so they could not do anything about it. On 10/20/2022, I was driving down the freeway, when I went to accelerate and at that moment the vehicle began to stutter/shake uncontrollably. After that, any time the accelerator was pressed it would shutter/shake. My vehicle was towed to a dealership. Come to find out, cylinder one was coding. They found out that the fuel injector was stuck open. According to the service advisor, that issue was causing a misfire. I was told that they replaced the fuel injector and the spark plug. According to the vehicle report I was given, 1 reman injector, 4 TS spring F In, 1 spark plug, and there was a core return (not sure what that means).

Good, not great

I've had the C43 AMG Cabriolet for just over a month, coming off of an Audi S7 lease. Some things are great – the cabriolet with the airscarf and rear wind screen, and the headlights are awesome. Acceleration in Sport+ is great, the handling is tight. Some things are annoying, but I can live with them – no heated steering wheel (thought that would be standard on a luxury car nowadays), no trunk release button on the trunk itself (every time I want to open the trunk I have to either look for the key button or pull the lever inside the car), wobbly and noisy windshield wipers that looks very cheap, no separate locking “beep” rather than the car’s horn (my daughter’s Honda Fit does that, but not in a luxury car), gas mileage worse than the V-8 450hp S7 I had. Wish I could program the Comfort mode to make it a bit more sporty – it’s very unresponsive with acceleration. I’ve set the Individual mode, but since it’s not the default setting, I have to always switch it on. Again, these are annoying, but nothing major. Maybe things Mercedes should be working on. Some things if I had known, I wouldn’t have leased this car – most notably the standard leather and Alcantara seats are terribly uncomfortable and cause me back pain within 5 minutes of being in the car (I typically don't have any back pain). I’ve tried numerous adjustments including the lumbar supports and nothing works. This is really a problem for me. The ride with comfort mode is still extremely stiff, feeling every bump in the road and makes the back pain even worse. Also there are no parking sensors. I thought this was standard on all luxury cars now and didn’t even look to see if the car had it. There is a backup camera so you can watch yourself back into another car - it's very difficult to tell how much room is between the car and whatever is behind it. And with the cab top up and the rear headrests, you have very little visibility if you try to just do the old-fashioned head turn to look out the back. So all in all, I’m somewhat disappointed with the car, especially the seats. Of course, coming off of an Audi S7 doesn't make it any easier, but I guess I’ll have to find some seat cushions or something to help for the next 3 years and enjoy the cab on those nice sunny days.

Awesome performance for a 4 cylinder. Great technology and comfort options. White with saddle brown leather and dark brown soft top looks classy. The details and quality of the vehicle is great.

i have not purchased Mercedes for many years due to the Chrysler merger. I mainly purchased /leased BMWs. The car and the technology is credible. It handles well and is fast. I have no complaints.
