I would not pay that for it, lots of previous owners, photos in shade and a front seat that looks poor, if it did not sell for a higher price recently I would hardly pay more for it! My previous one with high mileage had better interiors than most that claimed low mileage, I never treated the seats which kept the leather looking great & natural, a lot have had some crappy polishes on to try to make them look better, they only make them look like they are worn and require polishing.
There has only been one this year that I would of purchased, a blue one with 30,000 miles and 1 owner at £16250, it was 2006, even a 2007 one owner 27,000 miles one at £17,500 did not look well kept. I made a mistake not buying the former, however there will be other opportunities, I am in no rush.
