I work for BMW, You can lease an 09
Leasing a used vehicle is not as advantages as a new one.
The used vehicles leases are dollor based residuals not percentage of the MSRP, also their Money factors are not subsedized, therfore you are better off with a new car lease for about the same payments.
Also When you are buying an M vehicle, get it new and not pre-enjoyed one. If you decide to go for it or you like some numbers for comparisons purposes on a new one contact me, I will do it for you with no strings attached, if you like I will get you one for the same payment.
