Only time it's below 3000 RPM is when it's parked
I only ever drive on the paddles and thrash it given every available opportunity. *
I do a lot of miles (mostly motorway) and thought that cost of ownership would be lower on long life.
Clearly not if they charge twice the price though !
Then you are clearly not able to comply with the specific operating requirments of the LongLife servicing regime, and therefore, you would be very strongly advised to change to T&D servicing (but still use the higher quality LongLife oils).
Regarding costs, with the T&D service, then you only have to have an extra oil and filter change at 12 months or 10k miles, and should be had for around £55-65, if you use the price-match facilty, and even cheaper if you supply your own oil at cost prices.
Come resale time, and many potential owners who have "read up" and done some research, will know that the GTI really does need to be on T&D servicing, rather than LongLife - and whilst it is questionable weather T&D servicing will "add value", it will most certainly add to the desireablity.
