Has Ford actually said they are not going to build the MKR? I thought the designers had intentionally made that concept with normal doors (instead of suicide doors) so it could be made into a production car.
IF Ford hasn't killed any prospects for the MKR, then it would make sense that we are now seeing test mules for the MKS. The MKS concept came out a year before the MKR did.
If Ford does release the MKR (and tones the grill down just a small tad) I think they'll have a run away hit. Lord knows the Interceptor would be a home run. :D
