iv just nicked this off a differnt forum
but thought it might come in usefull for some people buying cars or trackday cars

http://www.dayinsure.com/

Had to move an engine last night, wasn't going to use my car and a mates car didn't have any insurance.

http://www.dayinsure.com/

2.5 litre V6 omega, Fully insured for £10.50 Very Happy Very Happy

Took about 4mins to insure it online, even printed out your own cover note

Fully legal, you can use the site to insure a car up to a month.

Even better was, Group 1-17 is £10, group 18, 19 and 20 is £20.

So if you happen to know someone with a rather expensive sports car you can take it for a blast (legally)

This site is perfect if you need to move a car thats been off the road, or if you happen to have a track day weapon and only use it a few times a year.

Only stipulations were that you can't have more than 8 points and been banned more than twice (or something very similar)

Dunno what forum this is best off in, but might be useful as a sticky somewhere?
