This is my 2007 Black A4 2.0 Turbo Quattro S-Line with Titanium Package. I havent done much to modify it . It came with Nav, Bose, Sirius radio, Xenon lights, BlueTooth, Convenience package, Black Leather, heated seats, paddle shifters and just about every other option. I hated the stock titanium spoke 18" rims. The gun metal color looked good but that was it. I added 19" Axis Matrix Wheels with a chrome lip and gunmetal center. I also added a APR octane program chip for power and debadged the back. I like it to look clean. I love driving this car. The AWD makes the handling ridiculous and you can really feel the control. The power is great and feels like you are flying. I also did a 25% tint all around. I did'nt want to go too dark because the car is dark enough. I am thinking of getting new springs to bring it down about an inch?
