You know Mr, considering the price of fuel and the environment, beyond basic point-A to point-B transportation there isn't much rationalization for anything other than a Scion-like "boxcar".
That said, the only other possible rationalization might be "grins"; but you don't need a ton of horsepower to achieve that. If you've ever driven a go kart you know what I mean; too bad manufacturers don't understand it. Maybe they were all deprived of the karting experience as kids, and now they're depriving us of some great automobiles as a result. IMHO.
I was glad to see that you included the Midget in your list. A buddy in college had a '73. I'm a big guy and a not a comfortable fit for the Midget (I fit into my MkI Cortina much better) but I sure as hell enjoyed driving it. Being close to the ground significantly increases the ya-ya factor so even if it won't blow the doors off of a 911 it feels like it will ... and that's
the point. And in my experience, if you happen to find the "right" 911 driver, you can
blow his doors off, as long as you're going downhill.
My dad restored cars as a hobby so I grew up with Ford Model T's, an Austin 7 Ruby, an AH3000, a TR-3, and an XK120. It's fun to relive the old cars through this current "retro" fad, but I think it's time to move on and create what will become "classics".
I pulled these images off the net.
Austin 7 Ruby
(a clunky looking little machine, but fun to drive)
But while we're on the "retro" subject ... the Jaguar D Type is still waiting for a proper redo ... something just isn't right in this excercise ... too big me thinks; lost the flavor they did ... needs those side pipes ... and the fin? Probably too much to ask for I guess. Like a retro Bugeye, I think the D would make a great "little" street car.
