The Skylark is too obstructed. The pic could be used for the Chevy Nova (White) but is commented in http://www.imcdb.org/vehicle_271202-Mercedes-Benz-SL-R107-1974.html and what you say it's a 55 Bel Air, is impossible to say if it's a Bel Air or not and, besides that, is too little to be added.

If APS221 is going on in this tv series as now, the page will be very very long and, probably, it should be in two or more separate pages. So lets try to add to this Series only reliable vehicles.
