That is a very nice collection. I have two of those UK RC Crossfires, however, neither is in new condition. The first one I bought was missing the remote control and after failing to find a replacement compatible unit I decided to upgrade it with a three channel digital Futaba RC remote and motor speed controller. I also upgraded the lights. It works but I have not fully assembled it back together. It's a work in progress. I'm thinking about repainting it to Graphite Grey to match my coupe.The other one is complete, but with a few play scratches on the front bumper. Like you I purchased a 110v charger. I also have a Silver RC car that is 7 1/2" long. The RC shown below is very interesting because the remote is also a wrist watch.
