there is enough info out there to find the residual % for this car, the money factor, as well as the invoice price.
calculate the invoice price on edmunds.com based on the options you have. it is accurate.
i recently just ordered a 328i, and all the info i found online (the 3 things i mentioned) were accurate. my dealer even tried to charge me .0018 money factor instead of .0015, and i called him out on it. the more you know the better.
