I am about to buy a clamp meter for car use any sugestions/experience. I know I need a high enough range for starting voltage tests and low enough for battery drain checks but anything else I should look out for.

I've got an ISO-TECH ICM36N (NTDWM)
Small, neat & simple AC DC ranges. 0-200A low range and 0-600A high range.
Never had a moments trouble. Batteries last for years. would highly recommend ISO-TECH. Use their Multimeters as well.
