Driveable miniature exotics!?

I received an email the other day showing pictures of a bunch of driveable miniature cars , Carrera GT, 911, Corvette, 360 Modena, etc.. Some of the photos show a person actually driving them. They look like 1/2 scale replicas, and look extremely well designed and put together.
Does anyone know where these may have come from? I am trying to find their website, but have not had any luck.

FAO Schwarz sells mini exotics, they are designed for the kids of the rich

check this out, a mercedes 500sl:

The photos I've seen have adults driving them. The Carrera GT is perfect right down to the brake calipers. I'd love to find out who makes them!
