Actually, you're conflating the history of the GM EV1 and the Toyota RAV4 EV. The GM EV1s were indeed rounded up after their leases ended, and most went to the crusher (although a few ended up being sent to university research labs, and one went to the Smithsonian (where it is no longer on display, for reasons unknown)). The Toyota RAV4 EV, on the other hand, was initially only available as a leased vehicle, but in 2002 Toyota sold around 300 RAV4 EVs to purchasers in California, and those vehicles were sold with no strings attached. Many of the leased RAV4 EVs also ended up in private hands after their leases ended.
Their idea of an offer you can't refuse is an offer... and you'd better not refuse.
