I was quoted $29,600 residual value (lease-end purchase price) on my $52,795 MSRP GT2, 0-down, 36 month lease 15,000 miles per year. As a percent of MSRP, that equals a 56% estimate being used by Kia finance at the beginning of July. Basic calculations indicates there is expected to be next to zero depreciation of the additional MSRP mark-up for the AWD portion of the purchase price.
In short, the market value of the AWD version is expected to maintain a $2,000 spread over RWD, at least through the first 3 years and 45,000 miles.... so, if your 52% RV on a GT1 RWD is consistent to the GT2 RWD, a lessor would get to use the AWD on lease for free.
Unless I am totally crazy and/or wrong on the math...
