vanity plates cause me to wonder what they mean... and this one? Is sorta odd

We know Jag models start with an X. 

XKR in this case... but CP50?

I looked that up and very strangely, Google returned with "Jaguar guitar distortion pedal". How crazy is that? 

The CP50 is still a mystery, but the similarity to a model number of a guitar distortion pedal is just uncanny... that a CP510 is Jaguar guitar pedal, and this Jag license plate is CP50, whatever the hell that is

So, does anyone have a guess what the hell this plate is supposed to mean to the reader?
