It’s got 230 odd miles on. It’s little more than delivery mileage. Yes, if genuine I would say that is decent value. It’s essentially unused with no wear/tear on seats, tyres, engine, anything. Someone buying that I would get it serviced at Jag, get the inspection done, get the warranty on it and enjoy it.
Buying a car with even just 10k on clock - when you put it in perspective - has done equivalent to John o groats to lands end over 11 times. 230 odd miles is brand new mechanically - if genuine.
