I do not know which one you picked, and I do not know which one I would pick either. Probably none of them, because I have not driven a car so far, and I currently do not even have a car driving exam/license, and I probably will not have those in the future either. By the way, these cars are very similar in appearances. Are they also similar under the hood? Both are BMWs (I also see the "i8" and "e63" amongst the tags), and looks like the left car is bigger, the right car is smaller. Other than these things I cannot really tell other differences.
