An inline six is almost always preferable to a V6, cetaris paribus, but I haven't found the V6 OM642 to be bad at all as far as maintenance is concerned. The turbo is right up top (which is good since the inlet pipe airways leaks oil), along with the fuel and oil filters, and there is plenty of room to work at the front. The air filter arrangement is a little goofy, though. The V6 also comes with normal brakes and the 7 speed transmission, and the general updates that came with the facelift in '07, but still has 16" wheels. Fuel economy is not as good with the V6 due to the more restrictive diesel particulate filter. Also it requires hard-to-find 229.52 oil to keep the filter happy. No diesel smoke either; not sure if that is a bug or a feature. I couldn't find an '05-'06 worth buying and my Bluetec was a low mile Okie creampuff so the choice was easy for me.
