The Jaguar XJL is an absolutely beautiful looking car from both the interior and exterior. We also know that some models have superchargers. You are able to hear the supercharger whine from the cabin, but have you ever wondered what it sounded like under the hood? I had the opportunity to do just that and have posted the link to the video below! I welcome and encourage feedback, questions, and suggestions! Please let me know what you think! Thanks!
