If its an ST TDCi it wont have Recaros as standard, only 220 standard fit. May have been retrofitted or its the half leather.

Search for the abundance of DMF, injector, EGR etc issues that come with the diesels, they can be costly if havent been done, may be cheaper to run a 220 in the long run.

As an allround car, excellent imo, never expected such a big car to drive so well and feel comfortable in long runs.
