The Spider-Mobile

Yes, by popular demand - The Spider-Mobile. Here's one of those 'Seemed
Like A Good Idea At The Time' things which never quite took off. Looking
back I guess it was a crazy idea, especially given the traffic in Manhattan.
What chance do you think Peter would have chasing The Human Fly down Broadway
at 5 p.m. on a Friday?
Spider-Man was contacted by Carter and Lombardo, a couple of advertising
executives, are looking for ways to promote a new non-polluting engine.
Peter thinks the idea is 'first-class dumb' and he tells them where to stick
it.
Later that day, however, he finds that he owes two months back-rent (long
story, don't ask). Pressed for cash, he decides to accept the sponsorship
offer. A month later in #127, he and Human Torch start working on the car,
in a room at the Baxter Building.
Most of the work is done by hand. Of course, one of Johnny Storm's hands
contains five spot-welders, and Spider-Man can lift the whole car without
too much effort. When finished, it looks like a red and blue beach buggy
- equipped with a couple of handy-dandy crime-fighting devices of course!
