Surely its the same platform, and just a variation of, the CX-T off roader, a very niche toy for very wealthy car enthusiasts.
I loved the 'life car' concept and was really happy to see it become the SP1. It was MMC showing what they can do. Brilliant.
As has been said many times, the CX cars are 'expensive' when compared to 'trad' chassis cars, and the question has been asked "where is the market". Perhaps bespoke cars for the very wealthy could be a profitably option for MMC.
I could be wrong, but I think I recall being told at the time, that it was built on one of the last Trad Chassis.
