About the Jetta...we weren't overly impressed with the build quality, and the reliability is questionable. So are you buying just for economy? In that case, the new TDIs aren't exceptional for MPG. We're still on the fence....we're looking for IQs next work car.
RR as you know, I don't put much weight in magazine reviews or whats on forums aka the greatest source of unconfirmed information. I worked in a VW dealership for some time and if I based reliability on that, I wouldn't buy a VW or any brand where I worked in service.
BMWs are supposed to be crap based on what some/many on here say. My friend's BMW is 27 years old and has required less work than my 13 year old Honda, yet my Honda is dead reliable and hardly needed anything. My BMW never had any issues either. If MBs are so damn unreliable, taxi service in Europe must be the pits.
I like the engine characteristics of a diesel; I get to drive them or in them when in Europe. As for mileage, its at least as good as the best gas engine out there.
Nothing from Japan does anything for me at the moment and recent past.
