Unfortunately working in the office on a live upgrade, such a nice day as well and would rather be outside

I would be tempted to go for the newer/lower mileage car purely due to resale later on. Always easier to sell a car which has less mileage on it and the 2008 is under the norm.
You will have to spend some money on the car but I reckon you should be able to get even more off as a bargaining tool. Thinking:
- cam belt is £300 (may be out on price)
- front pads £200 (for decent pads)
- MOT £50
Tyres £350 (all round) - may not be able to bargain on that as the seller will not see this as minus point due to them being new
Would show them this advert from a dealer: http://www.pistonheads.com/classifieds/ ... es/1234674 and let them know that their car is over priced.
