While they are definitely over-rated, quality is definitely superior to other cars in its class like the Peugeot 106, Saxos etc.
I have owned a vw polo 1.4L for two years and it has been completely trouble free, covering just over 20,000 miles. It is a shame that you have had such a bad experience with your car. As mine was a three door, the arrival of our first baby has prompted me to buy a five door polo, which I hope will serve me as well as my last one.
I had similar problems with the power steering pump and the electric window mechanism.
Basically the entire window mechanism had to be replaced (motor, frame and supports) as the initial fault snowballed and caused everything to fail. I ended up driving round for a couple of weeks with a wooden pole inside the door - much more reliable than the VW set-up! After having replaced everything the window still didn't work and given the constant fluid problems (also constant loss of engine coolant, which coloured surrounding parts of the engine with a friendly pink colour) I sold the car before it dented my wallet any more.
Bought a Toyota which is identical to VW in all important respects - handling, solidity, comfort - and not a single hint of a problem since.
Ask my neighbour about VWs. He's just in the process of taking VW to court about his recently purchased Eos. Three faults on delivery, two more since, and the dealer has now admitted they simply cannot get the electric roof working properly, and it will have to be completely replaced. The car hasn't yet done 2,000 miles.
Quality, my backside!
I have one of these as well, and it's been unreliable from day one, going into the garage every month with a new problem, most recently the starter motor. I have spent almost the value of the car on repairs. My mum's 15 year old Ford Fiesta 1.25 has had less problems than this. That's German engineering for you. Safe to say I will never buy another Volkswagen for as long as I live.
