It may not be much more per month to own a 200-series, but from my perspective, the bigger difference was the extra $10-12k up front. At the end of the day, there's just a limit to how big of a check I feel comfortable writing for a vehicle. I could walk into a dealership today and pay cash for a '14, but I never would (and if I did, my wife would kill me

).
I've got a kid on the way, a house to pay off, vacations to pay for, etc. While, the monthly depreciation isn't a huge increase to go to a 200, I wasn't willing to write a check for $38-40k, which is what an equivalent 200-series would cost in my area at least.
Anyways, brought it home today. First thing to go will be the running boards. Then I'm going to put some 33" AT's on it. Here are some pics:
