The cars we have been looking at are 2009's and 2010's grand c4, hdi vtr plus. We thought only some of them had turbos but obviously have now found out that all of them do. We are only going for a grand c4 if it has full service history. The cars we are also looking at have around 30 - 50k miles on them. The grand c4 we are currently very interested in has one down point. There used to be a larger person who drives the car, So when they got out of the car they held the top of there door. WHich now, when w eopen the door it drops down a little bit. If they can fix it befor then we will buy it. Thank you for your reply. Much appreciated
