Depends on a lot of things for me, mainly the condition and the standard of the repairs. Also what does he mean by full history, 3 stamps as per the miles (presuming service intervals on these are around 10k) or has it been serviced nearly every year as its been so 'pampered'.
If you were seriously interested i'd ask for the required info to get the owner history from the DVLA, if the 1'st and 3;rd owner is the same then the stories maybe true. Although id be quite suprised if insurers paid out what is probably 1/3 of the value of the car 9 months ago to get it resprayed.
either way id only be willing to pay around 5-5.5k for it as its a cat C and it effects the price accordingly no matter how clean it is
