Well what sold me was Shaq being the spokesperson for ZipZaps. I saw the huge cardboard cutout and I just said "wow, if I had one of these I could be a big black man too" and viola, I bought a bit. Since I didn't get a Zipzap, I'm not big or black, but I still feel like Shaq.

BTW I'm kidding. I haven't seen a single popup ad or received any spam email about these cars. I just think their appeal is the affordability and the incredible degree to which you can mod them. Plus, you can get cool cars like Skylines.
