Starter kit
Begin with an OBD2 scanner, battery tester, and multimeter. These cover the first decisions for many warning lights and no-start problems.
Second wave
Add a compression tester, brake bleeder, smoke machine, TPMS tool, or borescope only when those jobs show up repeatedly.
Buying rule
Buy for problems, not for feature lists. A tool earns its place when it changes a decision you can make in the garage.
