This is a brief explanation of the Difficulty Scale. I am not the most mechanically inclined person on earth. I am not even in the top 20% of the population. Obvious questions come up when someone who owns a Rover makes that statement. A few of my favorites are,
“Why did you buy a Rover then?”
“You’re not the sharpest knife in the drawer are you?”
There are others I’m sure you’ve heard. This is my scale. I have some friends that my 5 is their 3, notably the Evil German Dude and Jag Guy. They can disassemble motors in the dark, asleep, and not lose any parts. So this is the scale that I use to gauge how hard a project might be. There are five levels one being the easiest, five being virtually impossible for me.

A talented 5 year old could do the work. If you can’t do this level, get a 5 year old they would love to help.

You may have to read the instructions. Usually requires more than the Official Land Rover On-Board Tool Kit. You’ve heard “It ain’t rocket science.” That is a common term used for this level.

You are gonna get dirty doing this level. Mistakes like taking it apart and putting it back together more than once are common. At this level after you render the vehicle undriveable you will find you may need a new or special tool you don’t own, and must reassemble the vehicle to go and purchase it because your wife has the minivan.

Higher math skills desired. You will have the vehicle apart for more than a few hours. Pray for good weather or decent shop where the work can be done in a semi-climate controlled environment. Three-dimensional spacial skills are used at this level. A high degree of praying to the Rover gods wouldn’t hurt either.

The ability to understand particle physics is good here. Find a mechanic or an automotive Superhero that will work for beer or who owes you money. Often this level has conversation like, “No, I don’t know what happened, send a tow truck.” or “I think I have a Visa card with that amount available on it.”
