Full servicce History
is a good thing to have, cos it aint got one knock him down on the price, dont pay the same mnoney u wud pay if it did have one, also this will affect the price u sell the car for when u come to sell.
Give the car a good check over when u buy it.Check the oil etc...do it all properly and ask him/her if it has been recently serviced. U dont wanna buy a car thats been runnin on 3 year old plugs and filters as the engine will be rough as heel. Also check the cambelt to see how new it is. New ones are nice smooth rubber,old ones are persishing(flaky and rough)
What is it exactly ur looking at mate?
