Chewing advice V50, 2009

Hello all, I would like to buy a V50, for daily commuting (30km easy), vacation etc. Have looked at this today (but not yet tested): http://suchen.mobile.de/…/details.html?… Can you do something wrong? Which price is appropriate? Actually I didn’t want to spend more than 6000, but I’ve already seen that it’s hard to find something under 160,000km. But should hold a few years. Then rather one with 2.0? Important to me: little consumption. I didn’t understand 5 l, the “Drive” is less than the 1.6. I didn’t ask today, maybe the dealer also knows what. But would I be very happy about the answers too. To the previous owner’s story: first owner had it 1 year, second the rest. And: what good it is to buy from the dealer if you live 120 km away from him? Thanks already and many greetings!
