new Volvo XC-90-D5 for 2006

Hello XC-90, Elk community, since about 1/2 year I read Euro posts, since I want to buy at the end of the year also an XC-90 D5-185 PS automatic elk. As equipment I imagined : Summum vehicle color outside / inside : black / leather black, applications in silver alarm system tinted windows sunroof subwofer parking aid rear parking aid front ( hope in model 2006 there will be this ) speed-dependent power steering heater ( free !!! ) It will be my first Volvo and therefore I have a few questions to ask you : What is the long-term quality of the leather ? ? I was currently driving an Audi A6-avant-2.5 TDI with 120,000, which was sold next spring with 180,000 km, and I must say the condition was terrifying, wrinkling everywhere !!! What is the long-term quality of the processed materials ? I am currently driving an Audi A6-avant-2.5 TDI with 120,000, which was sold next spring with 180,000 km, and I have to say that it was my 3rd Audi, when I sold the chip? How do not have any use?
