Well, it appears to be a company *licensed by BMW*.  If so, I'd guess
they're held to pretty high standards.  This is not to say that the
models are great (I've seen some of the mediocre stuff BMW itself has
sold in the past.), but that the service should be good.  Personally,
I'd want to look at the models up close, in person, and then go buy
'em on ebay.

More than likely, as a builder (with a strong aversion to diecasts),
I'd *build* them.  In fact, I have.  I did the Calder Art Car in 1990
from a 1/12 scale Entex/Otaki kit.  I did the Ken Done M3 a few years
later from a 1/24 scale Fujimi/Testors kit.  And this week, I received
the Studio 27 decal set to build the Frank Stella CSL out of the ARII
1/24 kit.  If I find a good deal on the Lichtenstein 320i decals, I'd
do it.  I'm even thinking of doing the Warhol M1 either by hand or
with a decal set.
