I’m new here!

Hello. I finally got a Volvo yesterday. (V70 BJ05, 2.4D 185PS.) I’ve always been a Volvo fan and as soon as I can pick up the Swedes, I’ll be able to join you. Unfortunately I’m a layman about cars. Maybe you could look over the car I bought, even if it’s too late now. I’d like to ask you a few questions. 1. Can someone tell me how reliable or how good the Navi works? (2005 Model) 2. Mine has a Volvo. already 165000 KM on it. Does someone have so much, if yes, there were bigger problems? 3. I wanted to get a tub for the trunk, can someone recommend something to me? 4. I would need new summer tires soon (225/45/17). There are really many tires, can someone also recommend something to me. Limit was about 100€ per tire. 5. And finally I am looking for a page where I could order parts. For example, I am looking for a new cover for the trunk for the fuse box, at the old one. The plastic lever is broken. I had thought about scrap yard but maybe someone has another suggestion. Thank you very much. Greetings The New One!
