I want to get a classic Mustang. I am thinking of going with a six cylinder, for now, to save on gas. What I want to know waht kind of mileage they tend to get. I realize that there are many variables, mileage on engine, year of car, etc... I just want some ballpark numbers. I am hoping it is significantly better than 13mpg (what my truck gets) to help sell my wife on the idea. :SNSign:
