Alright time for the full story. When I bought my car 2 1/2 years ago, I very quickly found out the car wasn't as clean as I thought. This rear door had some halfassed bondo, and over the years it has gotten worse. The area around the door handle was also pushed in slightly. Luckily these problems were very hard to spot in pictures, so I've skated by, but I knew that I would need to get a new door eventually. When I picked up the new fenders I also picked up the door for super cheap, and figured I would try to make the A4 trim work on and S4 door. Finally did that and now I have a fancy shmancy looking passenger side for the first time.
As you can see, it is very hard to pick up that anything is wrong from your computer/phone screen

And that's my weekend making my A4 just a little cleaner
