x3X2 40 Deluxe.
A buddy of mine and I drove straight through from Dearborn, MI to Atlanta, GA one summer. 39 Ford coupe and 39 Mercury coupe. 800 miles, 18 hours. Average 50 MPH which is darn good even for modern vehicles. Fairly leisurely breakfast and lunch. When we got to Knoxville, TN we decided we were so close to home we would just drive on through. We drove 70 MPH most of the time, except for potty stops. Not too many white knuckle moments. lol
