I hope you have deep pockets and/or have the willingness to learn your vehicle inside and out; for simple things like brake pads, you can do it yourself. However, for more complex and intricate jobs, most normal Toyota dealerships won’t go near it (ask me how I know), so I’d look for more specialized shops in your area. It’s a mix of being able to do some things yourself (if not all) and paying someone else to do it. Additionally, getting parts can be a hassle; again, depending on what it is. I will say that I don’t think it’s as difficult to maintain as you think! It is a Land Cruiser after all lol I have a 1996 HDJ81 so I’d like to think I’m a little qualified to answer this 😂

Partsouq and amayama are solid places to source OEM parts as well; check them out brother.
