I'm in the middle off a ~3000 trip from SoCal to WA state and Vancouver island in the $1100 the c320 wagon. So far the only thing I've had to replace was a wiper blade. Auto wipers are my favorite invention at the moment. Oregon trucks with up to 3 trailers on the twisty 2 lane highway 101 require triple digit speeds to pass. A couple of family members flew into Bellingham to join me for the rest of the trip north which necessitated more storage space so I put a 15 cubic foot bag on the roof. This thing is more practical than any cargo box I've ever used and I can just fold it back up when I don't need it anymore instead of dragging it through the air all the way home.
