Unfortunately not the car I CURRENTLY own, but these 2 pictures, shot right after each other, are the best I've ever taken. I can't decide which one is better so here they are anyways.
Equipment was a Canon EOS 50D body + Canon 24-70mm f/2.8L USM lens + B+W 77mm Circular Polarizer.
Actually that car (MR '08 E90 M3) looks exactly the same as my current car (MR '11 E90 M3) from that angle anyways, so only I know that they're not the same. Still....
