MARK PETERS, PRECISION PORSCHE

“One of the first things you should check is the quality of the service history – not how many stamps it has in the book but the detail in the invoices. That’s where you’ll find information not only on oil changes and the grade of lubricants used but also on essentials such as belt and tensioner guide changes. I’d even look for timing chain replacement. Used parts are thin on the ground and that forces owners to buy expensive new ones, so be sure the 968 you buy hasn’t been neglected. For example, brake calipers can corrode, causing the pads to bind. I’ve known owners to file down pads to free them rather than buy new calipers!”
