Yeah, I used to think it was silly and expensive, but then on my current mustang I got "P52 FAL" and it felt like the plate was saying my mustang was a failed mustang (P-51). It turns out in NJ it is a one time $50 fee to get a personalized plate, so I figured I would pick what it said. The only issue I have is that I had to get them for the car I'm trading in, which I was expecting wouldn't be until February at the earliest. I applied for the plate on the 8th, and it took until the 20th for them to approve it - with an estimated 10 week wait to actually get them. Thursday I got a build date of 12/14, and although I should still have the plates before the car I am not sure if the DMV will get confused with a quick succession of getting a new plate, turning in the old, and then transferring the plate and registration to a new car. It is the DMV after all.
