Hey Scotty I have a friend that wants to buy a 2003 Land Rover with 102K miles I’ve told him repeatedly not to buy it but if he goes through with it what are some of the issue he might face while owning the thing
Land Rover is the company. Which model specifically?
You can try to look here: https://www.carcomplaints.com/Land_Rover/
It won’t cover every problem and is dependent on owners reporting, but it offers a glimpse. I also recommend you look at the online forums for that year and model including YouTube videos to get more familiar with issues.
Too many to list here when I look up the known problems on Land rovers on my data system there generally hundreds of pages. But it says money let him do what he wants as it goes we only learn by experience and bad experiences can teach a lot

Tata Motors CEO states (when asked about long-term quality issues with the Land Rover brand):
"Those cars are targeted at a market segment that is extremely focused on a luxury experience for an average of 2.5 years."

Translation; Expensive Yuppie junk.
What land rover? if a range rover: the air suspension and various electrical / electronic problems.
Best land rover is the defender (an older one), a bit agricultural though
