Highly optioned car listed for less that more basic models

I was looking at 2011 e550 Mercedes convertibles and a Olivine Grey E550 Cabriolet P88 Launch Edition popped up for a lower price than the other less optioned ones. Looks to be in better shape and the than the other ones listed. Usually they list the price of factory upgrades but this car said nothing about that. Carvana price is steep on this year E550 but it still seemed like a decent deal in comparison.
