Believe it or not, but there's a true entire scene that focusses on tuning like on the last picture: pasting colored cardboard on cars which is tuning. They usually consist of floppy bodykits, roadscrapers lengtening the nose with 3 feet and a spoiler that doubles the height of the cars. I am so happy I don't live in Japan, I'd move out to another country just to prevent seeing the fail they introduce to the world.
I only want customization of recognized and official tuners. BMW M, Alpina, Audi S/RS, AMG Performance Studios, etc etc. Luckilly TDU2 gets visual damage, I'll drive every ugly car I'm forced to drive in (race requirements etc) into a canyon.
EDIT: and yes, I hate Brabus. They pretend like they are RUF, but they do half work and charge you three times the amount of the basic AMG version. You'd be off cheaper if you got the Performance Studios to build you a one-off car from scratch.
