In my humble opinion, you need to get yourself a decent set of tool to fix your Land rover unless of course you have deep pockets to keep paying the garage bills....
I do but all metric. I do most jobs myself, but I do know when to garage it, no suitable tools, cold weather and dark early is a good reason.
Last year I replaced all the brakes, 5 years ago I rebuilt the ACE system, I have done injector seals, sunroof leaks, jammed CDL lever, jammed windows, all but one door lock, repaired with new switches and cases the keyfobs. Drop links a few times. All but one oil change (broken ankle). Hubs after a disaster at a different garage failing it at MOT and messing up ABS (fitted one myself been fine since.) Also fitted cruise. I just know when to bail out.
Just need to know your garages.
I have new headlights to go on but still need some clips and bolts, will do that myself.
Garaged it for the following, normally Astwood or MM4x4. When commuting I pass Astwood unless I go on the B.O.A.T. parallel to the main road,
Welding
Steering box
Gearbox pipe burst near work
MOTs (well you have to)
Starter motor (that cost £20 labour, to me worth every penny, while it was at the garage (was sitting there a couple of hours first) I did a few hours work and got paid a lot more than that.)
Next year I will do the radiator and intercooler.
