Isn't the Cruz diesel just now being offered ?
I think that means people who own one will have very limited experience.
I like to spend my money on models that have a performance history. Not trying to hype the VW here although I drive one.
Do a search for common rail fuel system on the VW's and see what you find. I'm driving a 2010 with my fingers crossed at +70k with no issues yet.
Their automatic DSG tranny was too new for me to bite on at the time though. Research there may also be in order.
