I called the guy yesterday to have a word with him and he will not go any lower than 6.5K. It's an insurance car and needs new front bumper, wing repaired, new windscreen, new door (ns) and he reckons a full respray. The car is a CAT C and is on the VIC register but you will need to call DVLA as it's not updated on the website at the moment. All in all the guy sounded very genuine. He could not tell me anything about the history in terms of camchain, Pads, Discs and other service information.
No way for 6.5K is it worth it imo. I am looking for the right car and I can get a decent car for about 10K. Look on pistonheads and there is a similar mileage Grigio car for 10.6K.
A CAT C will take about 30-40% of the value off when you come to sell so you need to be paying 30-40% less without the repair bill in the first place, it's 5K to put right part,s labour and service as I would not buy it without doing the camchains immediately.
