The Declasse Granger 3600LX is a modernized full-size four-door SUV added to Grand Theft Auto Online with The Contract update, and it is due to appear in Grand Theft Auto VI. The wiki notes that its design mirrors a real eleventh-generation American full-size SUV almost entirely, and in Online it takes exclusive Agency Vehicle Workshop modifications.
