Hi I'm looking at buying an S Type 3L petrol with 102000 on the clock. There is no record of the Cambelt being changed . Does anyone have an idea of cost approx before I agree a price for the car... I had a 3L xf portfolio diesel and I had that done at 70000 but paperwork went when I sold the car.. I had service and brakes and other stuff done so can't remember how much it was Thanks
