I'm sorry this may sound like a stupid thread but what's the difference between the rs4 and rs6 other than the time frames the cars were produced?
I've tried to figure it out for my self but it just seems as they brought out the rs6 and while they began to stop producing it then began to bring out the rs4 a slightly newer model..
