First tier, two points: The Lexus concept from Minority Report, the Audi concept from I Am Robot (not Tony Stark's R8), the police car from Demolition Man, Ambulance from Cannonball Run, Ferrari from Scent of a Woman.
Second tier, one point, can be tricky as being nondescript or less featured: Elanor, The semi from Big Trouble in Little China, '(Pretty please, with sugar on top, clean) The fuckin' car' from Pulp Fiction, the Bluesmobile, not to be confused with Green Hornet's Connie, the police car from Blade Runner, the mustang from Bullet which is not to be confused with the T-bird from Thelma and Louise, the v8 from Mad Max, a Ford Taurus police car (lol) from Robocop, the station wagon from National Lampoon's Vacation, Bond's submersible Esprit.
No points earned for: The Shaguar, Mutt Cuts van, Mystery Machine, Pizza Planet truck, Ghostbusters, A-Team van, General Lee, Nightrider, The Bandit's Trans-am, Herbie, Supra from F&F, Akira bike, the bus from Speed, Bond's silver Aston, Starsky and Hutch Gran Torino, Flying Ford Anglia from Harry Potter, the Cobra whatever-tank, Stairs Truck from Arrested Development, Mini Cooper from The Italian Job (every goddamn trailer and poster), BTTF Delorean, Mach 5, Cab from The Fifth Element, Halo Warthog, Aliens APC, Tron Lightcycle, Batman Tumbler, Lightning McQueen, Greased Lightning, Simpson Sedan, Keaton Batmobile, West Batmobile, Ricky Bobby's #62, Optimus Prime, Landspeeder.
That is not the RV from Independence Day. It might be from Terminator. One of those two angular things is from Total Recall, and I think both are from Arnie movies (Running Man comes to mind).
Ones I can't say I know: That Dusenberg looking thing, the yellow thing next to it, green lizard car, yellow mini, the two pickups that I think Dim identified, the yellow volkswagen van, the other green station wagon (no stuff on top), the green hearse, the green 2-1/2, the green SUV with blood splatter, black 80's sports car (looks like another Esprit), and the thing that is not the Dragula nor the Munster Mobile.
Why do I have such trouble with green things?
Disappointed to not see: Impala from Fear and Loathing in Las Vegas, the eponymous Gran Torino.
