Phaeton W12 Used purchase

moin, moin, i am normal in the volvo forum. i was now offered a phaeton w12 build year 06/2005. i have asked a couple of questions. before you have to pay attention to the phaeton, so which macking does it have? how is the consumption of a w12 (under 20l or over 20l)? super or super plus? is the navi cd, dvd or hard plate? besides, the price of about 52000 € at 11.200 km Einbische low. according to the list the car will probably lie over 100 k€. is that a normal price or is there special first shift trendy? thank you for your help. greetings sven
