First one is of Bangle talking about the design of the car.. (he's a great artist IMO) He talks about the cutting edge laser technology used to cut and shape the metal.. no pun intended.
the 2nd one is of the car in action.. absolutely beautiful sound. Sounds like they tried to mimic the sound of the original.. Oh, and that big diagnol slash on the back end of the car is actually the break light!
They put the inline-6 from the Z4M in it (latest version of the S54). Definitely sounds like they gave it a couple extra goodies.. I wonder if it handles well or if it is just a heavy art peice that just happens to move with a nice sound
