Have you tried editing your own dds files?
I mean, you could use all dds avaiable for all cars from this forum and combine them to fit your own taste.
That is what i have done and believe me its very easy. Its the same as editing you skins. I didnt know anything about it till 3 days ago and i started editing and was very very easy.
That way you could edit all your dds files. That will include a lot of object in the tracks that can be changed. Adds, signs, Team trucks, ligts, dashboards, etc etc. Do you want your "real life" car CD player on the XRT???. No problem. Take a good picture of it a paste it on the dds file. Do you want the FZ5 leather on the XRG?. No problem. Just look for that texture and paste it. Very simple.
Download a dds editor, i downloaded Paint.net cause somebody here recommended it and start opening your dds files.
that way LFS will look exactly as you wish.
cheers
