Yup, I agree, but I'd go further since sometimes the little dashboard screws have 4mm or 1/4" heads.
My dad bought me a complete Craftsman kit when I was 14 that included sockets, ratchets, screwdrivers, the works. Over the years I've accumulated enough to fill three rolling tool cabinets and still have stuff hanging on screws
My father-in-law bought me an excellent set of Crescent brand tools. Its a hard plastic case that folds in half and has darn near everything. All the metric and SAE sockets for 1/4, 3/8, and 1/2" drives, the ratchets, screwdrivers and a nut driver with about 40 inserts for any screw or small nut, needle nose pliers, wire cutters, extensions, adaptors, deep well sockets, allen wrenches, and metric and SAE combo end wrenches. Its a very comprehensive kit. Perfect for the junkyard
Aside from the specific specialty tools, that kit has almost everything you'd need, and names like Kobalt, Craftsman, Crescent, and Husky are good names. If you really get into it, you'll notice that certain tools aren't ideal for certain jobs, but its all about preference.
