IMO, this isn't something that would be your "regular" car, right? I have a Wrangler that's my fun car - I can't get a sports car up and down these hills, so a Wrangler with manual transmission and a top that goes down is the closest thing for me
But my Cherokee gets HORRIBLE mileage. I don't think I've ever gotten over 16, even on the hwy. Usually around 13 in town. I have no idea what the Wrangler gets because I have to figure that out manually and I'm too lazy ;)
