The problem with a tool set it included's sizes you will never use.
Every time you work on the car and get a tool, write down what you use. Soon you will have a list of the tools you need to buy.
You will end up with a few wrench's, sockets. Some extensions, screwdrivers and a metric hex key set, maybe small meter. It will fit in a small bag. I went a little overboard, wire, connectors, hose clamps.
You could go smaller, but this is what I ended up with,
