Is purchasing a second-hand Volkswagen Passat a good idea?

I've been considering buying a used Volkswagen Passat, but I'm not sure if it's a wise decision. Can anyone offer advice or share their experiences with owning a used Passat?

I've owned a used Passat for 5 years now and it's been a great investment. Just make sure to get a thorough inspection before purchasing.

I bought a used Passat and it constantly had engine problems. I would advise against it.

I've only ever owned new VW Passats, but I have friends who have had good experiences with buying used ones.
