V50 Purchase advice

Moin dear people, we have been thinking about buying a V50 for a long time. We found this model quite good:http://suchen.mobile.de/…/174757525.html?… It is a 1.6 diesel from 2010 with 45,000 km, which according to the company as a Vorwerk sales car ran and thus also has no checkbook entry. Maintenance was made within the company Vorwerk. The seller would give us a year warranty. What do you mean?
