Here is a link that shows all the XJ220S cars in the world. http://jaguarracing.wz.cz/Racingcars/xj220c_chassis.htm My Black one is 784, it used to be powder blue (yak). You can see a picture of it on *************. My titanium is 802 which used to be grass green (another yak). The yellow belonged to Tom Walkinshaw himself. Its whereabouts is in question since TWR filed for bancruptcy. The red one is in the Marconi museum but it does not have the numerous upgrades that I did on mine. I also have a letter from TWR indicating only 5 XJ220S cars were ever produced.
Cool, thanks for the info. I'll have to take the camera and snap some shots of the 802 titanium during lunch.
