the one red sports car was Sideswipe (used in TF2) who was a twin of Sunstreeker who was yellow, well since Bumble bee is a Camaro and not a VW bug i can only speculate this will be Cliffjumper (since Bumble be and Cliffjumper were suposed to be near identical compact cars in G1) or Wheeljack
OH WAIT CRAP this car might be BLUR!!!! he was one of the more popular main characters in the original TF movie and G2
and along with Blur other possible candidates are:
Chase -Throttlebots
Overdrive - Omnibots
Braver - Brainmasters (is a tipple combiner)
