We bought this vehicle with an oil leak, struggle to get them repaired it, at end the oil leak again surfaced and now we must travel on our expense all over to try and get this fixed. We doesn't want to use dealer near us and now we must travel almost 400km with 2 cars, left the one behind and again travel the 400km to get the car, which they first want to inspect to find out whether this is on fact the original leak
