Anyone who think Scott Kilmer is a reputable is sorely mistaken. Go find a real YouTube mechanic to get advice from. Car Wizard will tell everyone to just go buy a Toyota, but he’s a huge Rover and Jag guy and has owned several.
If you want to talk cost of ownership over time, my 46k mile LR4 was $28k in 2020. A LC200 with similar mileage would have been $50k. So far I’m into my Disco for $1400 minus oil changes and a set of tires, currently a little over 76k miles. I’d need to blow the motor in my truck and pay the dealer to install a brand new one to bring the cost of ownership close to the LC. My local LR specialist does the full timing chain service replacing EVERYTHING that comes off with genuine LR parts for $6500.
I will say that if you take a similar condition D1 and LC80 side by side, and baseline them, the 80 will be more reliable for a while. The D1 will always need some care here and there… usually nothing major but it isn’t as set it and forget it as an 80 is. However, it’s more comfortable, faster, and gets better fuel mileage than an 80… and more capable if the 80 isn’t factory triple locked.
