It was the B210, coincidently she owned 3, 2 being the 120Y's and 1 the 140Y SDX(running an A14). Then she also owned a 1600 B510, of which I posted a picture elsewhere on this site. I have been digging through old pictures to see if we ever took any pictures with one of them in it, but haven't foudn anything yet.
Wikipedia has an entry about the B210, and mentions the B210 120Y of ZA, strangely they mention the ones Tyrie like, 140Z/L14 and 160Z/L16, but not the 140Y/A14 one...
Wikipedia 120YMy car was also the 1200 GX, and also had the grill like the picture above. As Hendrik said, I haven't seen SEDAN GX's with any other grill, it was only the Coup
