Have a mess about on DVLA reg site. After a quick go I found plates from £255, not very interesting plates though.
Thanks Knitware. I've done just that, and come up with "GS05LXS" which is quite good (though probably lost on most people), and also "LX05MCK" (Lexus / Mickey). Both at £255, all in. Sadly, there are no numbers available which include "300", and "LEnnXUS" numbers are auction only. I'll return to this matter after I've sorted the possible ECU issue (see my other post). Thanks again, Knitware.

No problem mate. I would buy a plate from DVLA as they seem to be a lot cheaper than other plate dealers.
It's a pity about your new purchase though, you shouldn't have to worry about problems when buying a car, especially a Lexus. It's a pity you paid a deposit, my car has had the ECU changed and comes with warranty and a service plan, (winter tyres too) and I happen to be thinking about changing cars at the mo!
