8. Cadillac Escalade EXT – 1934 copies sold
General Motors announced that 2013 would be the final year for the Chevrolet Avalanche, the Escalade EXT’s down-market twin. Chances are that 2013 will be the last year for the Cadillac version, as well. All of GM’s full-size SUVs will be replaced in the next 18 months, and the EXT’s slow sales numbers indicate that this truck won’t stay around for long.
