I'm trying to I.D. a volvo that was used as a getaway vehicle during an armed robbery and was caught on a blurry surveillance video. Any help would be greatly appreciated an will be valuable in locating the owner and hopefully the subjects that are continuing to commit these robberies before anyone gets hurt.

Here's what I can see from the video:

1. it's a Turbo (five spoke wheels and black grille),
2. it has a sunroof -- don't know if it's power or manual, but it was in the vented position where the rear edge is elevated,
3. it has the body style of the mid/late 80s 740/760 line and has four headlights (which I think makes it a 740 from 1984-90?, or
a 760 from 1982-88),

4. it has factory fog/driving lights below the bumper in the air dam/front spoiler,
5. it has head rests for the back seats (someone said these may have been exclusive to the 760?)
6. color is silver or grey

Can anyone help? Let me know if there are other "identifiers" that will help determine exact model year.

THANK YOU!
