Trailer tail for a station wagon

[Andrew1]

Hi

I drive a jetta station wagon and was wondering if anybody here has made a tail for it like the trailer tail on the back of some tractor trailers.

It's nice that they fold up when not being use but I thought it looks nicer than a "normal" tapered tail or kammback.

What results have you seen and do you have any pics on how you did it?

Thanks
Andy
