Looking for thoughts on comparison of Eco vs VW TDI. Whether a Jetta or Passat, when equipped with TDI get approx the same MPG as a Cruze Eco. I am interested in the Passat because it is a (much) larger and more comfortable vehicle than the Cruze. I owned a 2001 TDI and found the experience mixed - incredible MPG and good handling, but had the usual set of maintenance quibbles. Is VW the same today? Is VW really any worse than GM? Anybody here own both? I don't like the TDI timing belt change interval and routine maintenance seems to be substantially more, but is it really?
