Not my first rodeo


but out of all the fun there comes a time for a DD and since AoA won't give me what I want as always I'm going to make my own, in this case I'm not going all the way in but I want to do something a little extra.
So I'm looking for an A6 Avant 3.0t, that I would like to do a mini rs6 conversion. I don't know how far I'm going to take this but as for now just keeping it mellow with hopefully some F&R bumper conversions and bits and pieces here and there.
The most important thing for me right now is to find a good base of a car and would like some input on any differences that can't be fixed or easily replaced like headliner for an example, rather find one with black headliner already in it. I know the car I'm looking for isn't going to pop up today or tomorrow even though I'm eying a few on the market now.
What is the main difference between Premium Plus and Prestige?
Is it purely exterior cosmetics but limited to front and rear bumper?
Interior differences besides steering wheels? (Is there a Heated flat bottom anywhere I can find lol)
Any performance differences as far as diff or anything else?
I'm sure I will come up with more questions and yes I did a search but nothing that really helped me out, I know it all depends on the car as we get weird ones out there that have been special ordered or the dealer made a unique combo when ordering but just looking for some general information right now.
Thanks
