From you pictures the 2 silver one are grand and the blue one is not. They have blacked out rear windows to try to keep temperature down in the back as there are no proper opening windows just the vent windows. They do have their issues, a lot of electrical problems, if you do look at one play with every nob and switch make sure it functions as it should. Issues with suspension and brakes are common due to weight of the car. My parking brake has to be stripped and rebuilt before every mot. Front nearside tyre wear is high again due to weight. They don't have front leaf springs. Only leaf springs in the rear. They are a big heavy car so it takes it's toll on many of the running parts, not a problem if maintained regularly.
