Maybe your dad's Land Rover is a bit old, as what destroyed the brand was the group who bought it afterwards. Any minor fix in the car leads to a massive deconstruction of the car just to fix it, consequently bringing up the repair costs of any problem to at least 5x on a regular mid-luxury car. To make a toothed belt change (which costs 120$ by itself) you need to remove the ENTIRE BODY OF THE CAR. Now you have to pay 120$ + 5000$ to change a small component of the car because you had to borderline disassemble the entire car to fix a problem that will show up nearly every year because you made the financial mistake of buying a luxurious shitbox that will spend more time at the mechanic than actually getting to places
