If you’re looking for the best C Class wagons out there, this looks like a very good candidate. With not even 10k miles, it’s practically unused and is said to run and drive like new.
Also, 2005 is probably the best model year for one of these because in that year (for the US) they got a mild refresh in appearance while retaining one of the best Benz powertrains ever offered – the M112 V6 + the 722.6 5-speed automatic. (In 2006, the new M272 V6 was introduced, which had balance shaft issues early on and generally speaking should be avoided through the 2008 model year.)
This one is offered on craigslist HERE by a private seller in the Washington DC area for $10,850. That’s a lot for a W203 generation C Class; however, it may be worth a premium to pick up such an unusually nice example.
