I have an old University analogue, a $50 digital which I got as it had a good range for measuring capacitance, but the one I use the most on the car for 12v is this one ....
AC/DC CLAMP MULTIMETER DUAL BATTERY SYSTEM TESTING ABR - NEW 12V FRIDGE TESTING | eBay
Having the clamp meter for measuring amps is brilliant, especially since it does both AC & DC volts/amps, plus the usual Ohms, Capacitance, temperature, diode/continuity tester (with buzzer) & also measures frequency.
