Most likely someone installed a short shift kit from a different model bmw. When done right this is an excellent mod. For some combinations you have to bend the shift rod. If it's bent out of line it will put the shifter left or right of center. You can take it out and twist it to put the shifter where you like. And when I say twist it, you will need to bent steel parts, so have a vice and other tools ready to accomplish this.
