A must have feature IMHO is an audible continuity tester.

i.e. when you touch both ends of the same wire you here a
beep...really handy for troubleshooting wiring issues and especially
handy for building/repairing wiring harnesses.

Hearing the beep is way easier than looking at the screen of the meter.

$10 multimeters at Harbor Freight even have this feature and are fine
for general automotive work.
