In this new series shot in Palmetto, people are forced to choose between cash and their clunker cars that have been turned into classic rides, all with the help of long-time race car driver Dennis Pittsenbarger and his mechanical mastermind Slick, who's worked on hundreds of cars in his Florida shop.
CBS Fall Preview, 8:30 p.m., CBS
This is a special showcase for the new shows in CBS' fall lineup, kicking off in just a few weeks. Get a peek at NCIS: New Orleans, a spinoff starring Scott Bakula (someone get this talented actor off this show!); Tea Leoni in Madam Secretary (smart, savvy, Good Wife-esque); hacker thriller Scorpion (why do people insist former American Idol contestant Katharine McPhee can act?); and Stalker (possibly the season's worst new show).
The Unauthorized Saved by the Bell Story, 9 p.m., Lifetime
Young actors play the original cast members of the '90s teen hit show in this movie that chronicles how Mark-Paul Gosselaar (Dylan Everett), Mario Lopez (Julian Works), Elizabeth Berkley (Tiera Skovbye), Dustin Diamond (Sam Kindseth) and others adjusted to life in the spotlight.
The Story of Frozen: Making a Disney Animated Classic, 8 p.m., ABC

SEASON FINALE So You Think You Can Dance, 8 p.m., Fox
With no elimination last week, all four remaining contenders — Zack, Ricky, Jessica and Valerie — head into the season finale. Unlike last year, when a guy AND a girl were crowned America's top dancers, this year there's room for just one winner. We're still skeptical anyone can beat Ricky, but Zack proves each week there's nothing he can't do. You know, like make it to this very competitive finals. Jenna Dewan Tatum pops up again as guest judge.
Franklin & Bash, 10 p.m., TNT
While trying to help a client win back his beachfront property (the poor sap!), Peter and Jared (Mark-Paul Gosselaar, Breckin Meyer) get messed up with a dirty cop. That's great, but what does Gosselaar think of Lifetime's Saved by the Bell movie?
Stand Up to Cancer, 8 p.m., ABC
Celebs like Gwyneth Paltrow and Katie Couric come together for a good cause during this night that aims to raise awareness about and funds for cancer research.
Outlander, 9 p.m., Starz
Claire, we know you're determined to escape this dirty, smelly, sexist 1700s timeline, but when will you learn, girl? There are eight books in the Outlander series. You're probably not going anywhere soon.
SEASON FINALE The Leftovers, 9 p.m., HBO
The 10-episode first season comes to an end, and we hope some of you are still watching. The Leftovers has been criticized for being too bleak or too slow, but we always feel compelled to watch, whether it's the town pastor's heartbreaking backstory or Amy Brenneman's continually impressive performance. It's a shame the best hour yet, Aug. 24's penultimate episode that focused on life the day before millions of Americans disappeared, had to come so late in the season.
