XF 

An Australian Ford Falcon which was produced from 84-88 (230 odd thousand made). Its not the best looking or fastest of cars but certainly kicks other cars asses in destruction derbys

Powered by the infamous 250 Crossflow (250ci came either carby or efi) engine this car had splendous amounts of torque to pulverize other cars.

often found with Bogans or Isajeeps driving them because of their relative cheapness.

oh and door handles screw up often

That XF just took out that Lambo without a single scratch !

XF 

The worst grade you can get in college, worst than an F. This grade states that you flunked the course because you were caught cheating. Think twice before you attempt to cheat on that test because if you get one of these grades, you are screwed the rest of your life.

Because he got an XF in one of his classes, everyone attempting to hire him knew he is a cheater.

The last Falcon Sedan made by Ford in Australia to have a full metal body before plastic bumpers became popular. An inline 6 cyclinder or 250 crossflow, has heaps of torque and is the first example of the more modern streamlined/smoothed edges on an Aussie car.

Big n beefy with plenty of style and grunt.

If an XF hits a truck, the truck driver will be killed. Instantly.

With a turbocharged XF, your lookin at around 550hp / 410kW. Awesome!

An 86 Carby XF can be left in the weather for 5 years without being started, taken out for a spin and totally smoke a Skyline of the same vintage.
