k8 - good point. And I just realised that we had a car that was only one letter away from that sort of plate when I was a kid. A nice shiny red XR3i, when my dad was going through his boy racer phase.
Despite not naming cars, I have half-heartedly named one of my guitars 'The Beast', because it's a red SG and looks particularly demonic (it gets played mostly in church...).
