I can only say what I read, that the new GW has the same motor with a slight hp increase, but it has lost weight so is a bit quicker. I'd like to have one but for the price of one, I can get a new awd Subaru or... TWO new C14's!
I can sit behind my keyboard and sneer that it is overpriced and slow but I bet if I test rode one, I'd fixate on buying one.
When you think about it, this might be the last gasoline powered GW ever. They seem to get a complete redesign every 20 years. Come 2038, I bet most everything by then will be electric.
