Yup. Yup. I drove a 1956 Volkswagen with a 36 HP engine in the late '60's. I also remember filling that 10 gallon gas tank for $3.00!

I guess my age is showing!

I sure don't remember having any trouble getting up to speed. However, I don't think I had any roads with speed limits much above 60 MPH back then.
I'd love to have one of those Smart diesels.
Subman, are you in SE GA?
