I used to think the same thing . I grew up in MN where rust was a fact of life . Then my brother in MN explained to me how many low mileage super clean cars there were around there .
Because we didn’t drive our good cars in the winter . I had a 73 318 Dart Sport Convertriple as a winter beater . Never drove my 70 Charger SE 383 magnum in the winter .
Makes a lot of sense in retrospect .
