“1952 M38A1 military Jeep. the Jeep was originally Air Force Blue when my Grandfather got it in the 60’s. He put an early 60’s Buick 174ci V6 in it. It was only used for elk hunting for a good 20 years and was always garaged. Last year it got a fresh paint job new top, tires, seats, seat belts, wiper motors(2) and exhaust. Brakes have been redone and new master cylinder. It has been n the family for a long time, just sits n the garage and doesn’t get driven.”
