Cordless drill/driver/impact for dummies!

Ok looking to get a cordless drill/driver/impact and to be honest there are so many for sale in different versions that i dont have a clue on where to start since i newer looked at these things before but now that my old drill is getting tired i figure i might step into the new world.


For general use in my home,garage and of course to work on my car,what do i look for and what do i look for?
10,12,14,18V
What brands are good?
Looking mainly at AEG, Metabo and Bosh but also the lower end Makita and Dewalt units since im not made out of money.
What kind of features are good in reality?


I have figured out that it probably pays to get one that includes battery(s) and charger and figure i may add a impact for heavier work later on so it would be a nice bonus to be able to run it on the same battery but dont know if this is a dumb direction to take.
There are units available with kits including a bunch of bits and drills do they tend to be worth considering?
Im also aware that the there may be differences betwen the Swedish and American marketunits but probably not much.
I have figured out that i probably dont want one of the supercheap ones.

Yes i am this clueless on this topic so feel free to give me the most basic advice!

Thanks in advance.
