So, it cost $10k on the Unlawful prototype to pick up .2 and will cost anyone else roughly $4k for ???

I'd go with Cal-Tracs or just back half the car. Both being proven methods. The Unlawful deal seems like a lot of BS for the money and the only ones who seem to back it up are friends of those who make it. Also, doesn't seem to be too much info on how well it works.
