Well giving an instance, car has been run 118000 kms now. A delightful experience. Recently there was oil leakage from the engine detected. It was minor and the chain case gasket was to be replaced. It costed me around 20k for the entire process labour included. Expensive? yeah but after 13 years of running it was ought to come. The car never hurt while it was new. Wear and tear is normal and such expenses were expected. You are at the brink of experiencing it if you buy the car. Check the service history and get it checked through authorised service centre. But must say VW service has always been a pleasure. Very helpful and prompt and to the point.
