There has been a recent onslaught of commercials featuring the number 43. MTV's G-Spot has a "next number" box that occassionally shows up as 43, there is a car commercial that starts with a 43 showing on the clock or some other fancy electronic; there are others. I was trying to find the car commercial today to post here. Googled "43 commercials" and found a Studio in Belgium that did commercial productions, Studio 43, but alas haven't been able to find the car yet.
I will keep looking. I can't even remember the type of the car though. Might be a hard search.
