2008 4dr Sedan 268-horsepower 3.5L V6
7-speed shiftable automatic RWD
Slow to downshift, so-so fuel economy in the city. Should really have 30 more horsepower. see full Mercedes-Benz C-Class review
2008 4dr Sedan 228-horsepower 3.0L V6
7-speed shiftable automatic RWD
Fuel economy is about averge for this type of car, perhaps a bit less, but not a major deal. see full Mercedes-Benz C-Class review
2004 4dr Wagon 168-horsepower 2.6L V6
5-speed shiftable automatic AWD
The city mpg is usually around 15-17 mpg. Now that's for a hilly neighborhood in a big city, but still. True highway mileage usually about 26 - that's reasonable enough for us. see full Mercedes-Benz C-Class review
