Before my time. My first car had 6v negative ground, and the 3 cell sat under the rear seat. Carb was metric, 30mm venturi, Solex. And it got 30 mpg at 60 mph.
'64 Volkswagen Beetle with sunroof as an option. Horizontally opposed 4 cylinder, whopping 40HP out of 1188 cc's of displacement, later turned into a 1384.
Sipping $.59 a gallon Regular was it's forte, not 1/4 mile times.
And for all of you Old Pharts, Volkswagen still makes the Beetle. With Moons.
And it will still get you to the top of Mulholland for the Submarine Races. In style. And the back seat is still a wee bit tight for fun and games.
