The Ultimate Reflection Machine

I love reflections, and black cars are really good reflectors. Plus, BMWs are awesome. I wish I owned one.

If you have any advice on what camera I should get, feel free to comment. I am looking for something that is not super spendy but that allows for decent manual control. I would prefer interchangeable lenses, but am open to other kinds too. I was thinking maybe a Micro Four-Thirds camera.
