The type 1 & 3 is both awesome, as is the Karman Ghia!
Before I came across my '92 HOnda VX I was going to go for a Super Beetle. Lighter than the Karman Ghia and best Aero of all the Type 1's. Curved front windshield is probably why. Better safety features, IRS of course that started in 1969. McPhearson struts in the front instead of shocks shocks so better handling. Then don't get me started about stopping, disk brakes, well the come in handy and the SB has 'em. You can get a Freeway Flyer transmission with taller gears and I hear you can build a very lean burning engine. Best thing is to put the oil cooler in the front of the car and take it out of the hairdryer shroud. The nice thing about the SB is there's a cool place to park an oil cooler in the front of the car. Behind the grill under the bumper.
Here's an article about building a sippy motor for a type 1.
