I've been tire kicking for the better part of a year. The old buick has been great, but its about wore out. I'm really leaning toward a vw diesel jetta. We put 20000 miles plus on a car per year and the longevity, resale value, and mpg are really appealing. Not looking to get a new one, but in the 2009-2013 range, lower miles the better. What I'm getting at is; are there certain years that get better milage than others, and what are some negative points to these cars? What kind of real world mpg are people getting with these? I hear of 50mpg, but is that exaggerated? 80% of the miles will be at 75mph on the interstate. These cars aren't cheap, but 50mpg sounds real nice, even if diesel is $.50/gallon more.
