Excellent gas mileage for a car this large (an honest 28mpg plus on the road). Good power, quiet, Only had one problem so far; a stuck relay kept the smog pump on after I shut off the engine which burned up the pump. A $1000 repair that wasn't necessary. Bad design here--- Overall i you get a good one, I think its an excellent second choice for a family. Its a better used buy then a C class. I wouldn't use it as a daily driver, though. Also, get a good, honest independent mechanic. These cars will send you to the poorhouse quick if you're not careful.
The ride is quite comfortable, classic look that doesn't look out of date.
Better quality control, I have small cracks in my dash and cracked interior trim. The transmission oil NEEDS to be changed every 100k; don't follow the OM on this or you will be sorry!
