I've never ever understood people that buy personalised number plates just to advertise the model name of their car. To me if people were genuinely interested in what car you were driving, surely they'd just look at the badge.

Here in my part of Australia we have personalised plates available with the top level being where you can order any (reasonable) combination of letters/numbers up to 6 digits for around $2500. They have recently done a limited release of 7 digits plates. I attended the auction and was amazed to see people bidding around $25,000 and then choosing things like CAYENNE. I mean are you kidding me, $25K to advertise the model of your car when it's clearly visible on the back of it already To me that's just insanity.

Even the limited run price of $3K for that is crazy. I understand (and have) your name or nickname or something like that, that is at least portable between cars. What are you going to do with a model specific plate when you upgrade?

Hope this longwinded response isn't too cynical (i'm having a tough day )
