I'm curious what car is it? I started thinking maybe a sporty car (thus gas tank is not huge) with a huge engine (bad MPG) but couldn't find anything, even a Viper seems to get over 300 miles on the highway. Maybe some Ferrari with particularly bad MPG? Seems the worst is a 812GT, but that has a range of just under 300 miles. So I give up, what is it?
