In Season 4 of Rust Valley Restorers, car restorer Mike Hall faces the toughest decision of his life: should he sell his beloved “Field of Dreams” and all of the cars he hasn’t yet saved? With new permit laws threatening to shut down his shop and fast approaching forest fires in the region, Mike is running out of time and money, and considers auctioning off his entire collection. Meanwhile his best friend Avery struggles to keep his own restoration business alive after receiving complaints from the neighbors, and Mike’s son Connor continues to help his father’s business while also planning his own wedding.
