Just a heads up, the actual car in 2004 with that livery had the enclosed wing supports like I modelled.I'll need to take some artistic licence with the wing supports... they are metal and open on the real car this was on, and are closed and painted on the model.
The images you are looking at are of the car much later in life with different spec everything, which is to be expected really as they go through multiple stages of regs, and those 'for sale' pics are just whatever it was racing with last.
