User reviews with long version requested

Since I am concerned with the decision about a new Phaeton, the question arises because of an attractive dealer offer: long or normal. I have already read about the legendary better driving comfort here. But I am self-driver, therefore my question about this everyday problem: How about the long one? Problems in the parking garage, does he look in parking bays in the rear disturbingly far out etc.? From my experience it is often difficult to find a parking space already with the “normal” version. Of the partly narrow Frankfurt parking garages quite not to mention. And here I do not mean the actual parking width which demands partly snake-like dislocations, but the partly only limited existing turning circles, etc. So, the 12 cm – felt from the driver’s seat – actually make much of it? Never driven a long version, therefore my perhaps somewhat naive question. Thank you for your answers.
