Use Phaeton with 150000km (after leasing) buy?

Hello everybody, I’m about to make a not-easy decision. And my Phaeton lease is about to expire, and I could also buy the car – or, my alternative, to buy a Q7 from 2013/2014, which costs about twice as much. The point at Phaeton is only the maintenance after a missing guarantee. The last 3 years I was the owner, regular maintenance and occasionally extra-scheduled workshop stay. Here are a few dates so that you can get the value of the car. VW Phaeton V6 TDI 176kW long wheelbase 4-seater 176 kW Diesel First registration: 09.2011, Now km-Stand approx. 150000. He has, as far as I can judge, full equipment with the exception of: wooden steering wheel, rear-entertainment, refrigerator. Equipment e.g. dynaudio temptation, acc, keyless, TV, telephone, return cam, heating, full leather equipment, soft close, side assistant. Single seats in the rear with climate, adjustment and Massa ge. What do you think – how will the next 70 000 km – “adventure” ? What is coming to me quite safely? If possible, a connection guarantee is still possible, that I ask. Thanks already for your assessment! Greetings take2
