The Cadillac BLS is an entry-level luxury car marketed in Europe by Cadillac. Based on General Motors' Epsilon architecture, the BLS was a heavily restyled version of the Saab 9-3. The development was done by Saab and the car cost more than one billion kronor (approximately $140 million) to design. It was manufactured in Trollhättan, Sweden, alongside the Saab 9-3 and the Saab 9-5. Sales of the sedan began in March 2006, with a station wagon joining the line for 2007. The BLS was introduced to the Arabian, Mexican, South African, and South Korean markets for the 2007 model year. It was never sold in the American market. The BLS was not successful; in 2007, Cadillac produced 2,772 cars at the Trollhättan factory, with 282 sold in Germany, a market with total annual sales of 3.15 million. Production figures for 2007 were down from 3,257 in 2006. Production of the BLS ceased in 2009 as a result of the poor sales.
