I have a steep driveway myself and I have to say that I can't even drive my car because it won't make it up in the winter with the slightest bit of snow/ice. The slipping/stopping that the front tires does is the most annoying thing I have ever encountered!

I just held down the gas and spin/stopped for at least a full minute and only made it halfway up my driveway. Even when we threw salt under the tires to melt the ice and give traction, the wheels kept slipping on the salt!
We thought we would be OK with the TCH as most people with front wheel drive can make it up our driveway no problem except for when it's really bad of course. As much as I love my TCH I'm ready to go back to a 4WD.
