She really enjoyed the MX5's. Her last one was a metallic white sport black. They gave us a absolutely no trouble apart from rusty wheel nuts every year.(which were changed under warranty) We were going to go for the new MX5, but they will only be a manual soft top initially. The Z4 is a new adventure. I'm not going to paint the flaps. The fronts were easy to put on, but the rears have a number of screws and clips that go through the wheel arch liner. However on one side the wheel arch liner has a heat shield, so it looks as if you need to take a lot apart to get the screws/clips in. I'm sure BMW would not make it that difficult, which is why I was looking for the original instructions.
