Just as a Alberta FYI rumour mill kinda thing,,, when I registered my car last year(July) I asked the registry lady how much custom plates were,, she answered the question with this: " I wouldn't recommend buying custom plates at this time because they may be changing the plate design and you might have to re-order and repay when the new design comes out"
That kinda shut the idea down of a custom plate for me,,, I'm too cheap to pay 2X for the same thing.
<Rant time: MOST of the plates are meaningless gobblygook,, and when you ask the owner, he or she gets all offended that their "brilliance" isn't oh so obvious to everyone else in the world,,,
Mine was going to be very simple: 79 L-48. Since last summer I've decided I don't need the extra "attention" of a custom plate. My 79 draws enough stares as it is. OK,, rant over>
