Name of a Horror Movie?!

I can't remember the title of this movie for the life of me and I can only remember certain details, I remember watching this film on television many years ago and I would love to find out what it was called!.

Here are the details that I can remember about the film:

There are a few men and women who enter a large house run by an old man behind a counter!. This old guy is played by some actor who is in make-up (wish I could remember who it was)!. The old man has two very large disfigured sons!. The house is right next to a giant junkyard or wrecking yard (where cars are crushed/ground up) The old man kills the men and women by putting them into a vehicle, and telling them that it is a ride!. The vehicle goes down the track and then goes into the grinder and it shows the remains of the people flying out the other end!.

Near the end one or two of the guys try to escape through the junk yard and are chased by the old guys two disfigured sons!.

Any help on this would be amazing THX!!!!!Www@Enter-QA@Com
