OEM Run-flats negate AWD on snow
Just a FWIW. Last week I had the first snow since I bought my C300 Cab w/4Matic, so I took it out to test how it would do on in-town, packed dry snow. It was terrible! The OEM run-flats are like slicks on snow and made the AWD useless. It was all over the road. I went 2 miles and turned around for home. My Cayenne has studded Nokian Happas so I'm not dependent on the Cab; which will stay in the garage unless the streets are clear.

If your cab has 19'' wheels then the OEM runflats are also summer tires. They suck in cold weather.
BTW, why run studs? You're in Orygun not Norway. Winter tires (studless) will perform better for 90% of winter driving applications.

There was a helpful post - asking if you're running 19's - and if you are then you have "High Performance" tires with Summer compound under 55 gets too dang hard - and at/under 45 kiss-ya-a*s-goodbye.
Live and learn - switching to "conventional" All-Season's on 19's isn't too bad - ...

All-seasons are OK for places where snow is occasional and light but are false economy in my snowy climate. I need solid snow and ice capability. I'm going to buy a set of 18s & Hakkas as winter wheels.

Take a look at some of the wheel and tires threads on here. The offsets for the 4 matic cars can be a little tricky. A lot of aftermarket wheels won't clear both the front disks and the control arms. If your cabriolet has 19''s and the sport package, then it's clearances will be identical to the C43/C450.

c400 was awd and shared the same suspension as the c300 and it shouldn't be any different from any other c300.

Many performance brands (Lamborghini, Porsche, Bugatti) that configure non runflats as stock supply a "Tire Mobility Kit" which includes a compressor and sealant instead of a spare. May work for basic punctures, but you'd be calling a tow truck for blowouts even on runflats anyway.

Are your OE runflats summers of all season? The ContiPros weren't that bad, but it was on soft/fresh snow, not hardpacked. Just switched to DWS06 non-runflats - these were fantastic in the snow on my Audi but haven't had the chance to test them yet on the Merc...

Summer tires (Continentals).

I had run-flats (17" Pirellis) until last year. No problems on winding, slightly hilly, secondary roads northwest of Boston. Admittedly, no deep snow, but plenty of light snow or slush over ice.

I'm sure they do. They are also all-season tires, not summer tires. They didn't have any flats from road damage, such as I have often read about in other threads of MBWorld, either. In the Boston suburbs, we have out share of wheel-breaking pot holes.

The OEM 19'' Conti tires are particularly bad in cold weather. I was a little late changing them out the first winter we had our c450 and it was useless after just an inch or two of snow. Michelin AS3+ do great in light snow and slush here at low elevations but I wouldn't trust them in the mountains.
