In 2003, Karen Pearson and Steve and Tara Carlson agreed to buy a 2004 Dynasty recreational vehicle (RV) from DeMartini’s RV Sales in Grass Valley, California. On September 29, Pearson, the Carlsons, and DeMartini’s signed a contract providing that “seller agrees to deliver the vehicle to you on the date this contract is signed.” The buyers made a payment of $145,000 on the total price of $356,416 the next day, when they also signed a form acknowledging that the RV had been inspected and accepted. They agreed to return later to have the RV transported out of state for delivery (to avoid paying state sales tax on the purchase). On October 7, Steve Carlson returned to DeMartini’s to ride with the seller’s driver to Nevada to consummate the out-of-state delivery. When the RV developed problems, Pearson and the Carlsons filed a suit in a federal district court against the RV’s manufacturer, Monaco Coach Corp., alleging breach of warranty under state law. The applicable statute is expressly limited to goods sold in California. Monaco argued that this RV had been sold in Nevada. How does the UCC define a sale? What does the UCC provide with respect to the passage of title? How do these provisions apply here? Discuss.
