It's all priorities I guess mate. Lots of people spend thousands just to get an OEM sat nav/audio/bluetooth. For what that costs you can have Stage 1 + intake + springs + clutch (if we did need it) and you're about even. And then of course, if you went for leather plus the OEM Nav/audio gear, an S3 kit would be looking cheap!
But this is why I love VW so much. I can choose what I want and work it to my advantage and my priorities. To my knowledge I cannot find another vehicle sold today that can give me this level of customisation and control over the car that I end up driving.
