Presently, I have a 1990 190E with about 80,000 miles on it--I've had a lot of problems. The local MB dealership has a 1992 300E 4Matic with 38,000 miles for sale. I know the 300E is a very fine automobile, but am I going from the frying pan into the fire? I've heard the 4-wheel drive is problematic and expensive to repair. Your opinions are very much appreciated! Oh, the price is $22,000.

Thanks,

Matt
