Capri
From Halopedia, the Halo wiki
On the Bungie website in a review for the Hog (A civilian version of the Warthog) near the bottom a vehicle is mentioned called a Capri.
Dynamically, the Hog is even more pleasing this year, and the aesthetic enhancements only add to its odd mixture of luxury and utility, though this is an update, not a revolution. Drivers expecting the kind of overhaul AMG demonstrated with last year's sublime relaunch of the Capri, will be disappointed, but for weekend warriors seeking a hipper way to bounce through the countryside, the '53 Hog is the only way to travel.

Note that 'Weekend Warrior' is most likely a reference to the 1994 Bungie game of the same name.
It may possibly be a luxury or sports car, for AMG in the real worlds is a special racing division for present day Mercedes-Benz vehicles and is also short for AM General, a manufacturer of American military and specialty automobiles most particularly the Hummer and HMMWV.
