Help with the purchase decision

Finally, we are proud owners of a Volvo V70 (2.4 140hp) *freuwieplöt* Our two Opels were already so badly broken, we should have put thousands of € into the rep. and have now exchanged them both for this giant flag ship. The stupid only… that belongs now to my wife. Admittedly … always wanted to have an E-Class. But after I drove with the Volvo … *sabber … tie … lechz… * Will also have one. Since we have to we already need 2 cars. On the Internet you will encounter the engineization of 140-250 hp (petrols) Now to the real question: Which is the best, least vulnerable and not too expensive in maintenance? Search a V70 or S80 from year 2002, gasoline, automatic The 200 or 250 hp versions are already offered quite cheaply. Very probably not without reason, right? (When I think of the Vectra V6 CDI … change glow candles once 750€ … ) Not to mention consumption. Think they won’t be less than 14l/100km. Why can’t you find a 170hp (or only rarely) one? Have they all ended up in scrap? Thank you very much for your help.
