John Bromfield is an honest young man with a pretty wife and a new baby. He's also a used car salesman, who gets fired for not pushing junk to a customer. That customer turns out to be the owner of a chain of used car lots, looking for someone like Bromfield to sell stolen cars.
HOT CARS, like many a Schenck-Koch production in this period, has an interesting story, people who look good on the screen and fine visuals. Not only is it shot in the "Southwest Noir" style, but there's a fine noir ending on a roller coaster. What it lacks is good performances. The line readings all seem a bit droning, like a bad episode of DRAGNET. It even results in calling attention to the actors. Joi Lansing, in particular, seems to hit her mark and pose before reciting her lines.
Still, the careful visuals and bravura ending add to the story to keep things interesting all the way through.
