Quote - I have no hesitation in purchasing the product. I meant his latest and greatest. I checked his store, which has some dreamland models (including one car), but I was unsure if that one car has it or just which products have the latest shaders.

Any product with BB's name associated will contain his unique shader setups.  Purchasing them does not restrict you from using the shaders in other products.  Use them as you see fit and necessary.  But be warned, some of those shader arrangements will make your eyes cross.  They can be very...elaborate.
