Thanks for the comments ! I will check the bump on the hood.
Tom, better than top/left/front/rear views of the chassis, here's a 3D, lowres blueprint of it. .blend file, open it with Blender to convert it to any other file format you want.
This is the wire cage I've made to understand the full chassis before actually modeling it (just by putting some cylinders on it)
Have fun, I hope it may be of interest !
edit : I zipped it because SMCars doesn't allow .blend files to be uploaded. Can any admin fix it ? I'm not the only nerd playing around with Blender
