What's that then? (I'm asking you before I ask Google)

The number plate on the eponymous Prisoner's Lotus Super7.

[Pen] Your windy miller has just shot up my list of admirable Hollanders. Seven years in storage, even with all those eyes watching, is rather off-putting so he drops one position. My car is a similar type. Down here they carry the generic name of 'Clubmans'. Mine is a locally built unit marketed as a 'PRB'.

[Dujon] Why do you think I married him? ;o)

If I had the money, I'd buy BDR 529

(Phil) Er, don't geddit. 529 is the square of 23 as any fule kno, and txtspk for 8.55. My own very costly favourite would be I TCH, obviously.

[Rosie] You'd avoid 1 TCH I presume?

I always wanted a 3rd gen Hiace registered as "Galileo".

[Rosie] The Bluesmobile, as driven by Elwood Blues. The number is actually a reference to the Black Diamond Riders, a bike club in Toronto (home town of Dan Aykroyd), whose clubhouse was at 529 Jarvis St.

[Rosie] N 1 TBN is owned by Chris Jeans, who was head of brass at my kids' old school. He was the guy who played the Flight of the Bumblebee for the Lurpak advert (and was principal 'bone for Grimethorpe, and other bands). His number plate actually has "No. 1 Trombone" in small print at the bottom. He's so modest!

(Phil) I've no doubt he's v good but God, what an egotist. Does someone that good really need to shout so loud?
(pen) I hope you avoided this.

Indeed, he does rather rate himself on the web site. He's a much nicer chap in person, although a little Hitchcockesque in his appearance these days!
