"...cigarette packs..." I always heard it was coupons that came in (or on?) Raleigh packs.

The price I heard for the jeeps was consistently $50.00. A family acquaintance told my father that he planned to get one, and Dad told him to try to get one for him too. In that instance no one tried to con anyone out of a deposit or otherwise scam them. I don't know if Dad actually considered it credible or not; he did mention some practical purpose he could use one for. I didn't go so far as fully assuming we were going to get one, but I had some hopeful daydreams of playing around in hills with one.
