Well, there was no edit button on my previous post, so I'll make my additon here.
For auto shop work, it's not usually a good idea to use an expensive meter. You need one that is of adequate quality and accuracy but somewhat inexpensive. The reason for this is that, unlike bench work, using it around a car it is very likely that you will drop it, leave it, place it somewhere that the leads get tangled in moving parts destroying the meter, etc.
It will cause many fewer tears to be shed when such a thing happens to an inexpensive meter.
Have a great day,
