Yes the old VW’s got great mileage. The first one imported in ‘49 had a 30hp engine. When they were phased out in ‘79, it was up to 57hp.
My ‘74 got 33 mpg but there was not enough extra hp to have an air conditioner.
Do we want to go back to that level of performance?
I wish I had a brand new 1974 Burnt Orange VW like I had. It was fun to drive and great in snow.
