The 1977 Renault #15 Equipe Renault Elf R.S 01 has an incomplete livery and the wrong shade of yellow. The livery decals that are missing include a number of sponsers that are already present in the game. Attempting to add these missing decals removes all the others from the car.
The colour of the car is also the wrong shade of yellow. It should be a brighter yellow.
Below are the images showing the difference between what the car looks like in the game and what it looks like in real life.

I have also included a link to a official Renault site that shows the car in a number of angles. It also includes a 360⁰ viewer of the car.
