10% is a good discount on a lower spec, however, since the MSRP is essentially at the MRM of $141,700 the discount would have to be substantially higher to offset the build. Quite simply, the car has way too much equipment. Additionally, the residual on a coupe for a 39/10k term is 58%. To the extent the OP is willing to shell out north of $130k or so, he might as well wait for the launch of the GTS.
