The wiper blade on the back of the mini cooper is a bit unique. To the point of being pretty annoying actually. You can't just buy a standard wiper replacement... you have to get the one designed for the mini. Also, wiper blade refills aren't generally well marked... but thanks to the Internet I found what i needed, and learned that you have to reuse the metal pieces from the original blade sinde the wiper isn't designed like most others. Oh well, I got it replaced and it wasn't *too* expensive (not too cheap either). Such is life!
