Purchase advice, what do I have to pay attention to? Volvo V70 d5 2.4 185PS

Huhu in the round :-)! After 6 weeks of stress with various used car sellers and the switch back and forth between Audi, BMW and Volvo, I am now sure I want to buy the above mentioned Volvo. Was a heavy birth, but actually Volvo was my first choice from the beginning only my friend wanted to inspire me for an Audi A4 or a BMW. Anyway, I have now found a nice V70, full equipment and very well maintained. Built 12/2006. What do I have to pay attention to? Tomorrow f I’ve already done a test drive and I’m thrilled. Can you give me a few tips? Is this a good choice? What’s the use? Thank you for your help 🙂 Eva
