We still own a Rabbit diesel! It gets 48 miles to the gallon in town and we got 54 freeway driving with it.
Well, I’ll chime in that my old Honda CRX (2-seater) got 65 mpg highway (or better) back in the days of 55 mph. It got around 48 mpg overall. No, it’s not a family car, but it was great for me as a single guy back then. It was actually quite a comfortable car for long trips, and I hauled some fairly amazing stuff around in it, for such a small / eficient vehicle. ‘80’s technology, too...
