Wow! Someone should post pics of these 4th generation CRX's! I've never seen one before!
(88-91 Rex's are 2nd gen for those who didn't catch my sarcasm)
Too much time on your hands I see..gotta nit pick everything.
but to get technical the CRX is still a Civic based car which uses the "4g" drive train and suspension and ineterior pieces. So a CRX still could be considered a 4th gen civic....
