If you are asking, could you physically do the job with inexpensive tools, the answer is yes. YES!
But you would need the start-up capital (money) to buy those tools. And what I consider a "basic set of automotive repair tools" could easily cost thousands even from a discount tool supplier. The days are gone when you could fix anything with a bucket of rusty wrenches and flat head screwdriver. Many GJ members like to spin that yarn. I've worked on cars whose oil drain plugs are 17mm Allens. Who even has a 17mm Allen starting out? It's a necessary tool. And we still have cars with SAE sized components. And if you are doing heavy equipment like
@Hakeem, you need full sets of both metric and inches as well as a large range of sizes (which gets expensive).
So this comes up from time to time and it sounds to Maria Antoinette: "The peasants are starving, they have no bread, what shall we do?" "Let them eat cake!". "Buy value tools" is good advice if the person has the money.
Otherwise:
Snap on offers students in tech schools 50% off on all the basic tools. You can also get a much discounted toolbox. You then pay them back weekly over a couple years interest free. So kids can start with 0 money. They can get federal aid to go to tech school, and get essentially free tools from Snap on.
These kids aren't imbeciles. They know debt is bad. Many start out with very bare bones sets of tools. The weekly visit to collect payments, replace anything worn or broken, and offer additional tools to buy is pretty convenient for them. It's not dumb. And they get REALLY nice tools that will seriously last their entire careers.
I've said many times, and no one likes to hear it: At 1/2 off, there's literally no way for these kids to lose. They can and do change their minds and sell off their tools, usually at a profit but at least without losing money. It happens all the time. Some of them buy tools on discount and instantly sell them at a profit. It's possible the profit would pay for cheaper tools. I wouldn't be surprised if kids did that.
Maybe this is why Snap on is the default standard. Maybe it's nothing more than the tech school discount. I've never seen an ad for Snap on. Not sure what marketing others have mentioned. Maybe its just the discount program.
