Pictures of the new BLS and other European market Cadillacs on this page, plus the next two (70 & 71). Note picture on page 71, the rear of an STS. Note reflectors in lower bumper facia. Very nice. Plus tail light lenses may be different from US cars. That, or a trick of the flash camera.

how much would the MSRP be for the BLS?

I don't know if that's been determined yet. It won't go on sale there for another year.

The smaller the car, the better Art and Science looks. Now if they stuck a supercharged northstar in that I bet it would seriously haul balls, but they won't and there's no room for one anyway.

I came across a good BLS article here: http://carreviewsonline.auto123.com/en/info/prototype/view.spy?artid=36813&make=Cadillac

Ohhh I love that STS
