The grill on the MMC is obviously much maligned. However, I had not noticed the rear end on the 2009/10 models until sitting behind one at a light yesterday. Specifically, it has some very nice changes with relocation of backup lights, the slight edgy design and trim strps. Looks Great!

I'm assuming the changes were introduced in the MMC

 

yes they were ... but i still prefer the RL before the MMC ... i think the rear of that car looks very clean

 

I have rear in my 2005 and I was envious looking at the new one.
