still searching around infos about this beautiful german racer,I found this nice website with a very detailed list of the cars involved. It is very clear the differences between years as well as the much wider body of the last cars of 1993,where also the front spoiler is completely different.
Being my idea to reproduce the WEST livery I should be quite ok with standard fujimi model, but many others famous ones have a slightly different body parts.
