I like the front hood with inlets and the front side add on arches.
But I dislike the rims, the back side add on arches and specially the exhaust tips. I think the quadruple exhaust distinguishes the 'M' from other BMW's. I think they could have gone with bigger round quadruple exhaust tips rather this rectangular dual exhaust tip.
Offtopic but I'm really impressed by Lumma's recent bodkit designs. They look really impressive.
Lumma might be listening to elegant people rather then wannabe's who want to stand out from the crowd with their ugly body kits.
