I can tell you how important is to find a cheaper plastic door handle that can save 1 euro on a car!
Even if they save half a euro-cent, or 2 seconds on not having to open a plastic bag to get a component out, they'll take it. Every last fraction of a penny counts in mass production.
And yes, the Mk6 is a overhaul of the Mk5 to save cost, refresh the styling and improve perceived quality - nothing more. But none the worse for that - the Mk5/PQ35 is an excellent platform.
On the subject of options - has anyone specified auto hold on a manual (std on DSG)? Do you get a little button with auto hold written on it? Just wondered as I used to have this in my Passat and found it useful.
