I believe all 1948 Pontiacs are Silver Streaks. That is broken down into 2 series, the Torpedo, and the Streamliner. The Streamliner Pontiac station wagon, then came as a standard and DeLuxe. The Standard, had the black rubber fender pad and no molding on the front fender. The DeLuxe had the chrome pad and a molding. I think that is all correct, as stated.Pontiac knew they could sell everything they made, with pent up demand from the war, so they loaded up the cars with accessories. The father of a friend of mine took delivery of a new 1946 Streamliner sedan-coupe. right after the war. It was loaded, except for whitewalls, which he couldn't get easily in 1946, but he did have a rear window windshield wiper, blinds in the rear window, a sun visor, tissue dispenser, big eight tube radio, underseat heater, oil filter, fog lights, and many other accessories. A really nice car to ride in for a little kid, that loved cars.
