The older MK4 Jetta's (2000-2004) have 1.8T engines that deliver over 180hp but also get 30ish/mpg on the highway if driven conservatively. IMO one of the best engines available on any vehicle. I think the current 1.4T's are probably just as good and I'd be curious to learn of owner's opinions on those engines.
The Golf's are BADAZZ, TOO!!!
