That's why you never buy a last of anything.
Same thing happend to the "Last" Convertibles in 1975.
Don't EVER buy a last, and don't EVER pay over sticker to be the first. Remember the 1990 Miata, and 1990 ZR1, Toyota Prius, Ect.... all very bad investments.
Except maybe the last 1967 Corvette,
That one is currently on "tour" of the USA. Turned out to be a VERY valuable car - Value $1M
