Is that Series 5 chassis #3, which was used by the factory for the very early test drives?
(If it is, I've driven it :-) )
If so, it'll have been well-maintained, used when warmed through, and won't have been ragged (because there would've been a passenger from the factory). And you'd hope that if loaned to journalists it would've been thoroughly prepped before & after. Not unlike Peter's development/demo Plus 8.
The only risk I see here is that the outer seat bolsters might have worn from many short journeys.
I'd be interested to hear what "eligible for factory bespoke customisation programme" means - does that mean they'll throw in some parts & labour at a good price, to move the car?
