"The problem with these kinds of "Customer surveys" is that each customer votes for his own car, which is not the best objective vote ..."
Given that that the VW Golf is Germany's top selling car, it's not rocket science as to why it's done well. I guess too, given that the Peugeot 206 is Europe's top selling car, it had to make it somewhere
In a sense, perhaps it's like some of these questionable airline surveys. How many of the voters have driven enough of the competitors to really make a fair evaluation of which car is the best.
Golf as the best in its class, bah! The only thing that does best is having quality, in particular in the interior. In every other respect, it's very much yesterday's car. The NA petrol engines are largely quite poor for performance and fuel consumption, handling is dull, ride is underdamped at times, less roomy than contemporaries, etc, etc, etc.
I've got a question for the Germans. Why is Opel so poorly regarded in Germany these days?
