The most basic list of all is the tools that came with the vehicle: Flat
screwdriver, #2 Phillips, 10 x 13 mm open end wrench.

You can add on from there until you have a garage full of tools.

I'd start with
#3 Phillips driver,
3/8" and 1/2" drive ratchets and breaker bars
3/8" and 1/2" drive extensions (short, medium, long) and universal joints
3/8" drive metric deep socket set
1/2" drive metric socket set
(3/8" drive metric socket set)
3/8" drive beam-type torque wrench
1/2" drive click-type torque wrench
(1/4" drive sockets etc)

12 oz ball peen hammer
16 oz ball peen hammer
Two or three pound hammer
Brass or copper drift for hammering on things without injuring them
(set of pin punches)

Set of metric open end wrenches
Set of metric box end wrenches
(Set of half-moon and/or s-shaped wrenches)
(Set of metric flare nut wrenches)
(Set of metric ratcheting box end wrenches)

Mechanic's creeper
Four wheel chocks
Four jack stands
(garage jack)
(pair of wheel ramps)
Battery or AC trouble light
Propane torch
Box 'o rags or blue paper shop towels (cheaper in roll than box)

Wheel bearing grease
Spray lithium grease
TriFlow or similar
PB Blaster or Aero Kroil penetrating oil
Brake cleaner

Cheap digital multimeter -- the $6 one from Harbor Fright is fine.
Some 16-ga or 18-ga jumper wires with alligator clips

I could go on for a long time but there are some things to think about.

Yrs,
