LOL! I am old enough to remember that color!
Although I never knew any ladies with one or "parked" in one :-) !
Speaking of targa, I've been kicking the idea around for a while, too, but mine would be side-by-side two seater, rear engine exposed on the side just ahead of a much wider race bike wheel/tire combo, rear wheel drive, with the whole vehicle elongated to help mitigate the gangly “pressed in a vise” thing that I was picking on this one about.
More sport oriented but definitely a more economical commuter as well, with a literal targa inspired by the original 911. Functional exposed chrome like a nice retro cruiser bike, tapered rear but not so completely tapered down like this, think Citroen SM. The whole thing would be fairly low-slung. I waver on the front end but you're looking at essentially a teardrop from above, cropped on the rear, “outrigger” wheels in front.
