I have to say those car transporters do look very basic and not very attractive in red either. I can also see how a long wagon like that is going to cause on some layouts as it will hang across the corner and catch anything sticking up that is too close to the curve. May even have some issues negotiating some tunnels I would suspect if there is a corner close to them. It's a shame in some ways as it would have been nice to see some similar length passenger coaches as they would then have been more like the scale length they should be
Happily collecting things all my life...
