RID/Car Robots was a great line. You should definitely pick up a few more figures. Though I'm not normally a fan of figures smaller than scouts, I do like the Spychangers. They have some nice colour schemes. I have the 4 you mentioned. When I got back into collecting in 2002, it was the tail end of the line and I picked up a few of the toys. On topic, I just bought the third party upgrade kit to turn the white CW Optimus Prime into the winged Nova/Nemesis Prime. Also bought the third upgrade kit for CW Devestator with the new head with the retractable visor and another alternate cab for Mixmaster. I've bought a lot of stuff in the last 2 months. Need to give myself a break from EBay.
