I'm going to buy a CPO ML350 this year, but can't decide which one to go, 2011, 2012 or 2013?

I assume 2011 will be more stable and 2012 will have more bugs possibly? There are very few choices for 2013 and hard to negotiate the price down.
Any suggestion?

BTW, should I go for diesel over gas?

Thanks in advance.

 

+1. My options are mainly 2011…but I have found some nice 2012s as well. Almost no 2013s and a couple 2014s. Seems like the market is flooded with 2011s - any idea why?

 

+ 1.
I am in the same boat as you guys..... 2011 better or 2012 and up!
