Thanks dmorozov, that worked fine in the sense that it returned only
unique years in a select box, but it still didn't order them properly
(getting non-duplicate years as 1961, 1931, 2000, 1975, 1995, etc.).
Somehow the order_by section of "set([(obj.year, obj.year) for obj in
Vehicle.objects.all().order_by('-year')]) " isn't performing its
function.
Any ideas?
Thanks again!
