Congrats on the car though! Nice specs! What dealership did you go with?
Beautiful ride. I wish I could have gotten a coupe, but with an 8yo boy it's not too feasible.
...cause lets face it, those rear seats are only there if you have leprechauns or munchkins...
Did the deal talk to you about breaking in the engine at all? Seems to be a bit of a debate about, so I'm curious to get input from others around NA...
Cheers!

As for engine break in. No one talked to me about it, but I’m gonna break her in based on the manual’s recommendation.

To everyone else, thank you!
Congrats though man be sure to post it when you take delivery!
It'll pay off when we get some snow here in the NE.Thank you!
Not that it matters because I doubt most salespeople have spent as much time reading and researching engines as me and I doubt any have worked in an engine testing lab as I have, but my salesperson told me on my test drive I could run it up to redline, just don't keep it over 4500 rpm. I've never felt like driving it like I stole it is a good break in strategy. I believe an engine needs high pressure in the cylinder to push out the rings and form a good seal. I always break in cars by driving them in pretty hard. Not race track or running from the cops hard, but harder than normal driving. I've seen proof an engine broken in putting around real slow like I stole it of using more oil and developing less HP. Most important though is don't push a cold engine and also take it easy on the brakes for a few hundred miles.
But honestly who knows nowdays anyway with all the new technologies and not knowing what is done at the factory. I don't know what MB does in the factory, they may very well be broken in. I would like to take a trip to Stuggart and find out, but unfortunately no ED on C43's.

i just got upstate NY last night, a lot of it was highway miles with no traffic since I left late but I tried to push the car to like 75mph then let it coast back down to 55 and back up again. I’ve heard highway driving is terrible bc you’re not really letting the car get through all the lower gears but I think my method was fine. I’ll be at 1000 miles sooner then I think and the obsessing over the much controversial “break in” will be over and I can finally enjoy the car.
