I have a good friend who's family has a one owner 1957 pickup. Short bed, step side, 6 cyl manual shift, small rear window, with an aftermarket Motorola radio. There is rust showing over the headlights, but thats about all. Ran until about 4 years ago, his "Mom" just parked it one day and has not been back except to crank it ocasionally to keep the battery up. Painted bumpers, never wrecked or even bumped for that matter. No engine problems. Has lived it's life on a farm in Tennessee parked under a metal shed when it wasn't working. What should I offer him for it?
