Other than engine specifics, what are the main visual differences between a DB5 Vantage and non-Vantage models? I've seen some vent badges that say "Vantage" but they show up on some cars and not on others. Also, sometimes I see a different badge on the grille than on the hood, and sometimes I see BOTH a grille and hood badge. Any help is greatly appreciated, as my company is trying to locate a Vantage model to photoshoot and we're unsure whether our local candidate is Vantage spec. Thanks in advance!
