Buy ok? and further questions

Hello Volvo driver, would like to buy this Volvo and have a few questions about it! Is the price ok? I could look at it myself. Actually looked very good for the age. What about the taxes? He has as much as I have already read here E1. You can convert it to E2. Only where can you have it done. (FVH?) What about the durability of the engine? What else should I pay attention to? Thank you! Greeting http://www.mobile.de/…/da.pl?…
