Sale of a Volvo V70 T1

Servus in the V70 Volvo round I listened to my son’s advice at the beginning of September and finally added a Volvo to me. It is a V70 T1 car with 142 KW engine and the first registration in April 1997 and proven running 317tsd. km. In the Volvo workshop of the seller I was confirmed that the car at 257 ts km got a belt change and a complete overhaul of the rear axle. He has always gone through the TÜV without any defects and has also another year Until the next examination. The defects that have not disturbed the previous owner I want to fix now gradually. These are : The air conditioning is without function The cruise control does not work The electrical adjustment of the exterior mirrors is broken, but as a new part with it and recently the passenger door has to be opened from the inside. So I immediately bought the repair instruction from Bucheli Verlag for the Volvo 850 and V70 for the model years 1994 to 2001. big, because although the newer V70 model is shown almost 90% only the 850 is explained and my V70 is not even mentioned in the motorization. Now I strongly hope that I am in good hands with you at the right address and that the one or the other from your round can help me a bit. I am looking forward to everything that comes to me now and thanks already in advance Rolf
