The Hyundai with 100K mile/10 year warranty is a more economical car.
Their Direct Injection Gas engines get good mileage... Accent and Veloster.
the latter comes with 138-hp 1.6L GDI DOHC D-CVVT 4-cylinder engine
or 201-hp turbo engine, Dual Clutch Transmission (DCT) and gets 35 mpg.
VW is the cheaper of the German cars, Audi, BMW, Benz, all very expensive,
to buy and maintain.
Consider yourself lucky you got rid of it before a catastrophic failure.
The CR TDI +2009 pushes the envelope and indeed has some serious
potential for catastrophic failure and collateral damage...
-HPFP failure taking out injectors and pumps
-Turbo failure taking out DPF and possibly EGR and CAT
-Serpentine Belt failure taking out timing belt and whole engine.
Does it happen? Yes. It is enough to be concerned because there is nothing
you really can do about it. There is no warning or no maintenance to prevent it.
