Hey everyone today my sister became the owner of a 2000 VW Jetta. It has the 4 cylinder engine. This is the first vehicle shes ever owned and I am not very familiar with these. The car has about 100k miles on it. Is there anything we should be worried about. Im away at college right now and havnt had a chance to run over it myself but from what she tells me it drives and rides fine. What are the main issues with these types of cars?

Thanks for all your help any information will be greatly appreciated.
