I hear ya mate, they take the pi**, this sort of thing makes me want to buy something else. At the moment a New Audi A3 works out cheaper spec for spec. I only managed to get 3% and a rubbish offer on the part ex against my old A3. I would say with the right garage you might get 7% as this is what fleet companies seem to get, might have to settle for 5%. Saw the post saying 12%, thats amazing (was it MK6 through uk dealer though?). Regarding the part ex price, you will never get the right deal for it through a VW garage, you need to sell it private. My other suggession is look for Second hand GTi if you have lots of bits on the option list, e.g. good deals on cars with Leather and DSG etc... Finally, as pointed out its all about demand and the gits at VW have created demand through limited supply, wait until March/April, by that time more cars will be coming though and more on the used market with another plate change in March. Delivery on new cars is about April at mo, so remember part ex value will fall on you car till then, so another good reason for used. If you are not happy selling private, try your Mitsi garage, they are more likely to offer more than VW, that normally how it works.
Could always go used MK5, not my choice but much cheaper option buy thousands and residual after 3 or 4 years would be not much different to MK6.
