TAG, short for Technique d'Avant-Garde, was a Geneva-based firm that presented a one-off, three-axle, six-wheeled luxury car, built on Franco Sbarro's design and called the Function Car, at the 1978 Paris Motor Show. Based on the 7-litre, front-wheel-drive Cadillac Eldorado, the car was aimed at wealthy Middle Eastern buyers and combined the utmost in luxury trim with every conceivable means of onboard communication.
