I'd have to agree with the above !! Here in the NorthEast the dealerships orders like 90% plus of their inventory with teh 4matics. I've learned to not opt for the 4matic and just get a set of dedicated winter tires/wheels instead which would save a couple of $1ks for the 4matic !In my humble opinion, 4Matic is a wise investment on a regional basis, especially considering the CLA is FWD. In snowy areas the investment makes sense but not so in snow-less parts of a country (while it may aid some on ice, nothing is truly effective where ice is concerned). Save the cash spent on 4Matic upgrade and invest it on the wheels or some other package.
I'm glad to see someone else shares my opinion on AWD in the snow. Blizzaks on our current FWD cars have proven much more effective in the snow than any AWD setup on all-season tires. I would definitely rather have AWD over RWD when things get slick, so I think this option is most important for the RWD C-class on-up.I live in the snow country of central Maine and have many years of winter experience in both FWD and 4WD vehicles (the latter an Audi Quattro and a Toyota pickup). Most of my vehicles have been (and are) FWD. On them, I run Michelin X-Ice tires in winter and they generally do just fine. I do need to be careful not to get off the road, in deep snow, or extremely slick conditions on a grade, but it is manageable. The 4WD adds a level of competence to that -- I can go through and over just about any surface so long as I have good snow tires. All-season tires just don't cut it when conditions get bad. A crucial thing to remember: people most often get into trouble driving on ice and snow when they have to slow down or turn quickly. 4WD does you no good for that, so it is not a panacea for winter driving. Tires matter much more than most people think.
One other thing: The Audi A4 Quattro handled really well for a sedan, and the full-time 4WD was definitely part of that. I would expect the CLA 4Matic to do the same.
