Great-not perfect-but great

Jim Atlanta , 10/03/2020
2018 Mercedes-Benz C-Class AMG C 43 2dr Coupe AWD (3.0L 6cyl Turbo 9A)
I’ve now owned my C43 AMG 4Matic for a year. Overall, I’m happy; yet, it’s not been a perfect experience by any means. I’ll start with the “bad.” It spent nearly three weeks at the dealership to fix a severe oil leak at 2k miles (Leaks =?more appropriate) The oil pan wasn’t properly sealed at the factory, and in two places the line to the turbo leaked. That was frustrating, if not … unsettling. Despite being dangerously low on oil, the notification msg only came on late into the problem. I’ve also had to have the passenger wiper motor replaced. Cosmetically, the panel between the moonroof and the windshield has a paint defect of some kind that makes it look like it’s been parked in the sun for a few decades. No amount of polishing/buffing has helped. It’s just the one panel though, and while I’ve not pushed the issue, technically MBUSA’s warranty coverage excludes this item. The infofrustration system is just stupid as hell. I don’t even attempt to enter GPS destinations anymore—luckily the Mercedes Me app is simple, fast, intuitive, and can send your destination info to your car with zero fuss. MB uses a subscription model for a lot of its connectivity functions, and the price is way too high for what you get. (Dear Mercedes—I just paid $67k for your vehicle. Can ya toss me a bone and just comp the subscription for more than a few months initial trial period? No? Okay.) The ride is Jeep Wrangler bad. I’ll never get over this one- I realize it’s a sports-ish car. But c’mon, there’s a reason ppl buy Mercedes vehicles, and it’s not to be jolted to the point presenting symptoms of shaken baby syndrome. Also, the steering-while predictable and adequate—provides a numb and non-communicative driving experience Other gripes: silly shifter, tiny trunk, backup camera distortion, useless infotainment interface. Abysmal dealer experience. Did I mention the ride? PROS: And there are a lot— BEAUTY Aesthetically, the design inside and out of this car is magnificent. It’s breathtaking at times, even. It’s faster than a lie from the president’s mouth—but only in the AMG version. The sport exhaust option is a superfluous and completely unnecessary, expensive option that defies logic, but I’d never want to drive one without it. When you get pst the turbo lag initially and start going at jail-worthy velocity —tap the upshift paddle and instantly it shoots the car forward and with a “POP!” You’ll swear a bullet fired right out of the tailpipe, grinning ear to ear the entire few seconds you have until you either run over the car ahead of you or Mr. PoPo hears what he swears is a shootout and pulls ya over. Would I buy the same car again? Absolutely.
