Pay attention to this one. In British English, the final R usually disappears. So words like car and door don't end with a strong R sound. Here's the thing. You stretch the vowel instead. Car sounds more like ca. Door sounds more like do. Listen, this is super importante si quieres sonar mas natural, porque no es caro ni door, sino mas suave, mas largo. Quick note, if the next word starts with a vowel, the R can come back. Like car engine, example. That singer left her car outside the arena. Esa cantante dejó su coche fuera del estadio. Keep practicing and see you tomorrow.
