Nobody's mentioned axle stands - 2 pairs of heavy duty.

And the Swarfega has to be green - don't think much of the Orange.

ive got a 1/4 drive socket set from halfords that i bought about 5/6 years when i had my moped just to put under the seat.
i use it on every single job i do, its the fist thing i grab when i have to work on a car.

but today i bought a milwaukee m18 battery impact gun
gotta say a trolley jack is high on the list as well
