| Leather, rust protection, climate controls Well, I have so many questions but I'll try to start with only a few. I'm a repenting BMW owner, and the new C class, besides looking quite elegant, really seems to promise the kind of car I'm looking for.<p>Anyway, the U.S. cars both have leather, or partial leather as I understand it, standard, and premium leather is an option. I haven't seen the differences discussed yet, does anyone know what they are?<p>Second, I understand Mercedes uses body cladding under the car to replace the cosmoline coating for corrosion protection, and also to help aerodynamics. Anyone know if this creates additional issues driving through flood waters? I'm worried about water leaking in there.<p>Third, do I understand correctly that there are visible differences in the HVAC controls between the two U.S. models?<p>Thanks for any help!<br> |
