There were so many differences between the 3 models it would take up volumes listing them all. To the average person getting used to telling them apart the easiest way is to look at the tail lights, bumpers and grills with the exteriors and also looking at the interiors. XC have the BIG bumpers. XB front bumper looks like a Mach2 Mustang. XA front bumper comes to a slight point at the front to match the extended point on the bonnet. XB and XC have the same exterior door handles. XA and XB have the same interior door handles. Man this is just getting confusing. Get some photos of the different models and start comparing. It's a lot easier that way. You'll be spotting a XB GS Continental at 200 yards in no time.
