In LA they're chronological also for the first number. My grandma's 96 van was 3TOR, my dad's was 4KEH, mine two months later was 4LEE, my mom's a year later was 4T or something, my bro's is 4WAV...now i notice that the new accords are in the 5's. trucks are different. it goes 1a2345 where cars are 1abc234
personalized license plates range from 60 to 90 per year depending on what you want from the dmv.
and i'd say a good half or more of all corvettes have personalized license plates in CA
