This car is amazing! I have had over 48 mpg on two tanks of diesel. It is solidly built, quick, and fun. This car is worth every penny and should not be passed up if it's available. I am not sure how it will do for winter driving, but I suspect it will be fine. For me this car is better then any hybrid and compromises nothing in quality for fuel economy. I hope more car makers look toward turbo diesel technology, it is truly awesome.
Fuel mileage - 48 mpg on the highway and 37 mpg in town, UNREAL! Also, the sun roof is nice too.
Make a different dashboard light scheme. Other then that, nothing, except to bring the Passat TDI back.
