I totally like the idea since my GF and myself enjoy riding the bicycles. How do you get on to the roof, and off, without some sort of stepping stool, or even a ladder? I probably would scratch up my roof pretty bad without help.
I think the body is wider in the back and the car has a squared tire setup. Who knows what's going on. I myself showed it to a buddy of mine and it reminded him of a Plymouth "Superbird" like the one below.
I use my BO CD player because I am too lazy to rip things to USB, plus I can never find the right USB to begin with when driving. Plus its impossible to navigate the USB when full of ripped CDs, at least for me. The dash menu never works, or is laggy.
CD in, play, enjoy the drive.
