E63 vs GLC63

Back again to get some more questions hopefully answered.

I’ve always been more of a sedan guy, but I want something that can handle Michigan snow and temperatures.

Considering I drive about 15,000 miles a year, I wanna make sure this can get me back-and-forth to work without many issues in the snow. I 100% understand I will have to put winter tires on both of them, but I’d like to get 40 to 50,000 miles out of those tires.

So I’m wondering if I should just stick with an SUV over a sedan.

I also understand that these are AMGs, and they’re gonna be expensive to repair when need be. I’m just wondering if either of these are more reliable than the other.
