LS-swap all the things! If there's one major detriment to Tesla's image as a sustainable, eco-friendly manufacturer of emissions-free pure-electric vehicles, it's the company's stance on repairs and rebuilds. The automaker maintains an iron tight grip over the parts market for its own vehicles, and more often than not, when a customer car needs a significant amount of attention, Tesla would sooner guide that customer toward buying an all-new vehicle than repairing the one they've got. But all else being equal, keeping an already-built vehicle on the road is generally much more sustainable than purchasing an all-new one. That's part of what inspired YouTube's Rich Rebuilds to embark upon a Tesla Model S V8-swap project.
