Rahal Letterman's livery for their Porsche is somewhat underwhelming. Actually, it's flat-out boring. I don't know what their Porsche looks like this year (or are they even racing in the ALMS this year?), but let's hope their BMW M3 is a little bit more "exciting."
Only 'marginally' less boring then the Porsche at first glance, but the all-white body is something special for BMW race cars (V12 LMR and LM98, Original Parts Car).
