Before we found out we needed I minivan, I was seriously considering the Passat. IMO its ride quality is heads above Camry. It's much better composed, for such a big car, it is quieter and smoother as well, but has that nice firmness that the Japanese cannot reproduce. The Accord is not bad, but the Camry is simply terrible.
The room inside is also the best in its class. For all intents and purposes, it's interior is of a full size sedan, no midsizer can touch the Passat for that. The trunk size is on par with others I think.
The interior fit and finish is excellent, IMO better than Camry and about the same as the Accord. I also liked the simplistic look, but that is more of a personal preference. I hated the Accord's 2 LCD screen layout, same with the Odyssey.
The 1.8 is a DI and a turbo. Some may not like it but the Accord is DI as well, not sure about the Camry. It has lots of grunt down low, which is where the majority of driving takes place anyway, and runs out of steam a little at high RPMs. The Accord at least felt nice when wound out, but in the Camry, yuk. In any case, none of these are made to be high revved and their ATs keep the RPMs low, so having lots of low of torque in the VW felt the best. The transmission is a regular, 6 speed automatic with the torque converter. Not the DSG unit and it is proven to be bullet proof. Also, unlike the old 2.5, 5 cylinder option, this engine returns very good fuel economy. At the time I was considering a TDI, but with the 1.8, the TDI made little sense unless someone drives a lot.
All in all, I felt that the Passat, at least not the fully optioned up version, should be on par, as far as reliability goes, with Camry and the Accord, but it has that premium feeling, even though it was cheapened out and not the same as the European version, and will not remind you that it is an econobox the same way as the Accord or the Camry would.
