MMC should try and resolve a no frills "Poverty Spec" CX.
It wouldn't be slow either but an entry level under the Plus Four might just be a good seller. Like they did with the Runabout. Limited palette and options etc etc.
Nice idea, but I'm struggling to think how they could get the price down low enough to attract a new, different tranche of buyers. Could they get near the £45k of a Caterham?
