I started with a half in square drive socket set and a 3/8 inch square drive set. A good set of screwdrivers, a set of combination spanners and a hammer.
I then bought more tools as I needed them.
With all tools buy the best you can afford.
Many places will sell you a basic tool kit to get started.
Good luck.
start with a simple set of tool. you can get it at any store that sells tools. lowes hardware, home depot, sears, etc. they run any where from $50 and up. the more pieces there is in the set the more it is going to cost.

You will need metric tools. SAE sizes haven't been used on cars since the 80's.
A set of sockets and ratchets is petty much useless without a wide range of extensions and adapters.
You'll need an ODB, ODB2 code reader, or code scanner, or diagnostic tool.
When a car's Check Engine Light comes on, this is the tool that would tell you what is wrong with it.
Then you get your socket wrenches, screw drivers, multi-meter, torque wrenches, etc.
start with a basic mechanics toolset available at most any store, and a set or 2 of good endwrenches. rome wasnt built in a day, it takes time to buy tools.
Trying to get into working on cars, and have no idea where to begin.
