Q: They say its in good condition, but I really want to know how many miles it gets on a gallon of gas.

A: mileage isn't bad, but you really need to check for is rust. they were really bad for this. even if the body looks good i reccomend that you get under the car and inspect the frame and the floor. look for any holes big or small and also look for any patchwork that may have been done. remember, rust never sleeps and if rust repair isn't done properly it's just a matter of time before it returns.
