Because people will pay it, just for a status symbol.
That is exactly it. My Vagabond is way more comfortable, faster, more responsive, you can see where you are going when its on the ground, has toe brakes, and costs half as much. I am 6ft and weigh 230 lbs, I have flown in the front seat of a J3 ---- not my idea of a good time. I'll keep my little Vagabond thank you very much. Besides the Vag is yellow and to alot of folks if its yellow its a cub, go figure.
LOL J-3 a "status symbol". Y'all are clowns...assigning d-baggery to others who simply have different taste in airplanes. I'm taller than you and would take the front seat of a J-3 over being squished next to your oversized butt in the Vag.
