I am looking at picking up a new 2012 550i. It's a pretty big transition for me since I will be giving up my 09' M3. I love my M3 but with two kids now, it's just not practical anymore. Details of my deal are below, I would love some feedback!

2012 550i (build date of 4/12)
Dark Graphite II, Dakota Black, Anthracite Trim
Convenience
Cold Weather
Driver Assistance
M Sport
Premium Sound
Sport Shift w/Paddles
BMW Apps

MSRP: $75,045
Selling Price: $65,200

Trade-In on 09' M3: $45,000

I feel like they are giving me a very fair price on my M3. It's one of the big deciding factors for me to do this deal. They pay it off and cut me a check for the remainder since I am leasing.

MF is .00145 and Residual is 54% on 10k. (only put 19k on my M3 in 3 years) I have not gotten an exact monthly quote yet but my hope was to be right around $800.

My other option is to order a new 2013 but I am not sure I can get what I want in the same price range. I hear the residuals are higher on the 2013's though so that might make a difference? The 550i on their lot is close to what I want but not exactly. If I placed an order I would not get driver assistance and I would much prefer to have Nappa leather and the rear shades for the kids. (not to mention the new iDrive)

Thoughts?
