I think if you want to compare resale values between two cars, you need to factor in that the MY2010 was probably sold in 2009, and you should compare the 2009MY vehicle's actual selling price (probably 5% to 7% less than the MSRP stated). That difference over three years is not abnormal. The "$89K " amount actually sounds a bit high for the 3.5 X6.
