Residuals are always for 15k. Add 2% for 12k and 3% for 10k.They don't tell you what the millage is for the residuals they supply. Are they basing the residuals on 10k, 12k or 15k miles per year. No one knows.
The 2012 and 2013 factors seem to be the same........doesnt make sense.http://www.ridewithg.com/index.php/2012/08/2012-13-bmw-lease-rates-august-2012/
