Looks very nice, nice colour too; has all the right options (GT, rays, parking sensors, sat nav). Problem is the mileage and this is what's making a huge dent in its value.
At this mileage following should ALL have been done, so check:
* Services - A total of six - FP1 (9000), FP2 (18000), FP1 (27000), FP3 (36000), FP1 (45000), FP2 (54000), next would be FP1 (@ 63000). [note these are 'FP' services, not the normal 'P' because of high mileage use; not sure of the exact difference but are identified diff in service handbook. Worth phoning the servicing garage as well to check stamps are genuine (more likely to be faked because of the number that were required)
* Brake fluid @ 36000
* Cambelt and platinum spark plugs @ 54000
If all that's been done and you really like the car then make an offer. I'd say 16000 (max) though.
(I guessing they paid over the odds not realising true worth and so in turn are trying to get an uneducated buyer)
