I think of vanity license plates a little like tattoos – it’s almost impossible to find a single idea that is so important and timeless it won’t look a bit silly after some time.
Bragging about your job on Wall Street is a little foolish when the market tanks (especially if it’s attached to your sweet ride [it’s a Maserati] – it’ll make me [for one] wonder if you’ve made your latest payment).
I saw this one (on the bottom) shortly after noticing the Maserati – the only interpretation I can get from it is “GM stocks” –it’s on a GM car. But considering the shape the car industry is in, it’s not a great thing to brag about right now (I hope his pension isn't at risk).
