请简述这段话的重点，不超过5句话。 Joanna bought a new car yesterday, a shiny red convertible. She has been saving up for it for a long time. Today, she took it for a spin on the highway and felt the thrill of the wind in her hair. However, she noticed a strange noise coming from the engine. She is planning to take it back to the dealership to check it out.

Joanna昨天买了一辆新的红色敞篷车，这是她长期以来的梦想。今天她在高速公路上试驾，享受着风拂过头发的感觉。然而，她发现发动机发出奇怪的声音。Joanna计划将车送回经销商处检查。
