Ben Those all look great! If I had to pick one that really stands out I'd say the second ("message power") -- "M" valve cover style really looks good...I like the overall concept - not sure about the text though...."message power" sounds a little corny. I would brainstorm for some different text ideas with the M cover concept.....the 3rd & 4th ideas are really good too...on the third one maybe darken up the "BMW" portion & experiment with some different colors....just trying to help! Good luck! -Aaron
