Ray, the first red F5000 car is ( I believe ) Ken Smith in a Matich A50 or A51. We have a photo that Dad took of it sitting lop-sided on a standard car trailer, possibly from the same meeting as your photo. The Matich was too wide for the trailer and the tyres on one side are sitting up on the trailer side rails. I've always wondered what happened this car.

#41 is a Lola T430, which David Abbott owns ( 2 of them, both ex team VDS, one of which Ken Smith drove for a few years ). Only 3 ever made, Todd Stewart owns the 3rd one ( ex Haas ), it was on display at the NZFMR last year.

The white car, and the next photo yellow and black car are Lola T330 or T332's.
