Saab NG900, gets rear ended;

The main characters get married in September 1993 and get rear ended two months later (November 1993), but they do already drive a Saab NG900 (produced from 1994...).

The SID does not look like the one in a 1994 900, more like a 9-3 (1998- );

I made the images from the trailer: http://www.imcdb.org/movie_1606389-The-Vow.html
