One of my favorite "B" movies is HOT ROD, an ABC 1979 made-for-TV movie. (Not to be confused with the 2007 "Hot Rod" movie) It's as cheesy as they come, the definition is fuzzy, but once again, it was made for TV back in 1979.
The two main cars in the movie are a Hemi-powered Willys and an Oldsmobile 442. It stars Gregg Henry and Pernell Roberts. I've seen this movie sold on ebay before, but it's hit-and-miss.
Two thumbs up!
