The Acura RL, which last had a total redesign in 2005, has had a hard time getting a foothold in the marketplace. A facelift in 2009 helped, and updates in 2011 kept the sedan reasonably fresh amid a raft of updated competitors. However, that clearly was not enough – the RL landed also on our list last time around, and its numbers in 2012 sales were even worse. Part of the reason for the dismal sales results was a dwindling inventory; 2012 marked the RL’s final year on sale. Acura has already shown the 2013 RLX, which will replace the RL as the brand’s flagship sedan when it goes on sale in March.
