Best car?? How about the Ford Model A built 1928--1931
300 cubic inch four cylinder. No spark plug wires, manual timing adjustment on the steering column, no fuel pump, no heater or AC, the floor boards were boards, high ground clearance.
Many older model A's were modified and used for farm tractors. Some had a second transmission installed behind the original to give added power at the wheels. (after market heaters were available -- open the windshield for better summer ventilation)
