As I am sure you are aware, the general forums are all riddled with problems, regardless of the car. BMW, Merc, Chevy, Toyota, Audi, Honda etc.
It is completely reasonable to not love the cars, and not want to buy one. I just can't relate to them being unreliable, but you can.
It really depends on the model, as with any car. Pick them wisely, and you will be rewarded.
I will continue to be a VAG lover, until they stop producing a car I want to buy, for the price I am willing to pay. At that point, I will buy something else. Haven't had that problem yet. Although, the CTS V and corvette are about the only cars that have come close.
