Purchased a '08 North Edition used and drove for 4 years and 160,000 miles. Outside of normal mtc. such as oil/filter/air cleaner/tires/brakes, the only 2 issues I saw were an intermittent failure of the crank position sensor(which caused a misfire idle) and a failed #6 glow plug(needs a 11mm deep 1/4" socket to fix). Beyond that, the Mercedes CRD powered vehicle was fantastic. The transmission was very stout, but needed an additional gear as the 5-speed had the engine running 2100rpm @ 70mph(3.73 gears were standard). The swirl motor was a known failure point, and eventually would fail(the resulting fix was to electronically fool the engine into thinking the swirl motor was still functioning with a $1.39 resistor or actually replace the swirl motor @ $4563.00 labor & parts charge). That engine was designed to go 1,000,000 miles before a rebuild, the transmission was rated for 500,000 miles. Superlift made a 4" suspension kit for it(designed by AEV-conversions), and the rest of the drivetrain was quite stout. As previously mentioned, the Quadra-Drive II with the ELSD rear AND front diffs is the winning choice, but the Qaudratrac was no slouch either. Interior space was small by todays standards, but works ok for 2 adults, a kid and a dog.
