I bought my RL new with 6 miles on it. It now has over 205,000. This rascal has never let me down and while components have failed they have been silly things (trim across back glass, and cup holder gets stuck now and again).
The EGR system and driver/passenger seat belt buckles were repaired/replaced under warranty. I've had to pay to have a passenger window regulator replaced ($450), front chin spoiler two times ($125ea) and the rear window trip three times ($125ea). Other than that...everything works as it should.
Others complain about power but I don't have any complaints at all. This car moves when I want it to.
My "older" car is a 1988 Legend L 5sp coupe with close to 380,000 miles.
It's not really a "feature" but I really love the syling of the RL/Legend. The long low look is just sexy. I'm hoping the 2013 will be retro.
