In reply to Tom Ripley Mountain Guide:
As already stated above, there are a number of matters that can haunt a low mileage car. However, If you are ready for them then it is still worthwhile.
CLOCKING
This means it is a false mileage record. Maybe through tampering and maybe through disconnection(s). You definitely need real evidence. Old MoT certs are good. Local knowledge of the owner is also good. The mileage record should match the state of the vehicle.
SHORT JOURNEYS
These are hard on engines and often on clutches and gearboxes. The classic is does it jump out of second on the over-run? Intermediate gears may be heavily worn. The engine may never have warmed up properly in its whole life. There is no undoing the extra wear that will occur in a cold engine but if its a genuine 25k then just be kind to it and it should be fine.
ACCIDENT DAMAGE
It no unheard of for a car to sit unused after and accident for a long period. This will usually happen in the case of a severe legal dispute or an uninsured event.
BRAKES
Brakes like to be used. A low mileage car of this age will often need complete replacement of several brake parts. Check for recent work on brakes: discs, handbrake cables ... .
RUBBER
At 6 or 7 years old, many the rubber parts start to degrade. The ones like wiper blades are most obvious but this is affecting brake systems and that nightmare of vacuum pipes and air hoses in the engine compartment. There is a huge variation in the prices makers charge for these small rubber hoses and complex mouldings. For instance, I have always found BMW ones are quite cheap and Volvo really expensive: no idea about Skoda.
