V50 T5 AWD Aut. buy or not buy this is the question

Hello people Why I turn to you has a very simple reason. I would have just had a V50 T5 AWD Aut. BJ 7/2006 with 78000km on the watch at hand. The car is in the best condition and also fully Volvo partner service provided, so the engine has nothing to assume about it and you can also find no report that it is a vulnerable engine. Only I can find no or spooky information about the Volvo 5gang automatic and the AWD. Are the prone ones? Do they perform fault-free or are there known defects?…….. I want to buy a car with which I reckon with a teure reperatur “MUSS” I thank you already in advance. MFG Rudi
