The +4 is, indeed, a piece. However, it is limited to the appreciation only of the cognoscenti. As you are in Houston, you will get infinitely more bang for the buck from the M3W, as you will have to explain it to no one..... they will come to you wherever you park, looking for your autograph.
Of course, I know that those matters are unimportant when it comes to cars and their owners.
