The ECO system might be good but it is still inside a GM POS. The people I know who own Chevy/Buick trade them after 3-4 years because they are falling apart. Interior fit/finish is a joke and parts fall off when you go over a RR crossing (no lie-happened to a co-worker 3 months ago in a Chevy Cruze).

I've given up on USA cars. Chrysler selling old line junk and cheapo Fiat/Alfa's that the Techs still don't know how to fix. Ford is a Techno Joke because the 'Lectrinocs don't hold up past 18 onths or the supposed software/firmware upgrades actually DEGRADE the control system.

And do not get me started on MB...
