XC 70 bj 2003 a good offer?

Hello, there is a change of vehicle with us and I have been busy the last 4 weeks with the vehicle choice and the “problems”. I have now found the following vehicles:http://home.mobile.de/AUTOhandel-JABER#des_169257364http://www.autoscout24.de/Details.aspx?id=220509076&asrc=st It should be a car as easy as possible, am I there on the right track, or rather without XC take the 2.4 petrol without turbo? Important is 2 ml in the year 1.5t caravan approx. 4000 km Otherwise only 2 * 20 km per working day. I have the feeling the more you read it becomes the more complicated … Thanks already for your assessments. Greeting Jonas, wife and 2 small children (3+1) PS. at the moment we drive an espace from 2006 as diesel, which doesn’t like short distances at all.
