Dave -
An option for an inexpensive body would be:
http://www.amazon.com/Revell-851752-For ... B007KMY2WS(the Anglia body you have sounds like it is 1/24)
Another option you may want to explore is contacting some of the guys here on the boards that are doing resin casting. Lot of possibilities from that angle. :)
In regard to the motors - there are specific motors required for each of the classes - they are detailed out in the first posting - but for the majority of the classes it is the Piranha 21,500 Motor (available through Slot Car Corner, Cloverleaf Racing, etc) - for the slingshot dragsters and the Class A Land Speed cars - it is the H&R Lightning II 40,000 rpm motor (available through various sources)
Hope that helps!
Oh - and one other thing - I misspoke on the manufacturer of the timing system at Mark's Model World on the drag strip - it is a PortaTree Eliminator 2000 Plus system (the other four tracks have Trackmate - sorry for the confusion)
Also - just for reference - a little more of things can be seen in this video from last night...
The video doesn't show the numbers up on the LED display at the end very well - but they are also shown and will be recorded/shared directly off the controller seen in the beginning of the video.
