The easy answer is yes, and most likely that is the correct answer. The question to ask is whether the wrenches and sockets are metric, a requirement in the US for anything less than 20 years old, and in most of the world for all years (with the exception of the some British makes)
Modern cars also require many tools that aren't used at all on older cars, and some older tools have no application on modern cars. Things that used to be simple, like removing a fuel line or bleeding brakes can require special equipment. The diagnostic equipment is totally different, but actually easier to use.
Don't feel like I use many tools on new cars anymore. Everything's going electronic so I spend most of my time with diagnostic equipment (scan tools, multimeters, oscilloscopes, test lights, retractable jumper leads, etc.) and once I find the problem it doesn't take but a few minutes to fix. Usually just a plastic trim stick, 7mm, 8mm, 10mm sockets, electric impact driver or ratchet, and push-pin pliers is what I mostly use.
new cars uses metric sizes. Although some size are very close ie 13mm vs 1/2", etc.. it's not an exact fit to not strip the bolt or nut. There are also torx bits sizes that new cars uses.
A hammer fixes everything.
My father is a auto mechanic of old cars and has every tool needed to fix older cars.Do they work in new cars.
