It is not that they aren't great cars, because they really are. I just drove them a bunch when I had my Scalextric track, and they didn't like the wood tracks.
A set of PGT urethane tires trued along with the wheels, hot glued the motor in, did the axle super glue trick, opened the mounting holes a little for a float, and glued the bushings in. They are fantastic now. I really enjoyed playing with these great cars again.
I managed to get 7/10 done, but I'm whipped after a busy week and a busy weekend ahead!
