Just got this about 3 weeks ago, has around 100k miles on it but looks like it's brand new. I want to add onto it a bit (not a whole lot) and change some things, like the paint job. So here come the questions. I'll include a (pretty bad) picture of the car.

First, is it possible to install LED headlights on an older model of the A6? I really love the look of the LEDs on the newer cars and I'd like to put some on mine. I was told that aftermarket LEDs would not be worth it and that OEM headlights would be the better option. However, the shape of the regular headlights and the LED headlights are very different so I'm not sure that OEM headlights are available.

Second, I'd like to get a matte paint job but I don't know much about them. Something like gunmetal grey or black, just a dark color. From what I've heard, scratches won't really buff out and they can be pretty expensive. What can I expect from this type of paint job?

Those are my two main questions for now. Possibly going to plasti-dip the wheels as gunmetal grey and hopefully it looks good with the current paint.

Any information you guys can provide will be really helpful, this is my first Audi so I could use some help lol. Thanks!
