Id bet not one guy in 500 has a milling machine in their garage, but for the few guys that make the leap to having the tool to do the custom work,, most of us always want but darn few of us can afford to buy, after you have one and learn how to use, the more advanced tools like a mill,lathe and a TIG WELDER, even for very basic work, its amazing how things progress and together with a decent TIG welder the WHOLE concept of building/fabricating and modifying O.E.M. or custom parts becomes far less intimidating
A mill will easily cost you 7-12 times what a drill press will, but its also easily capable of doing FAR FAR MORE than a dill press can do, in fact a skilled MILL operator with access to a LATHE and the correct tooling for both machines and a WELDER can make about 80% of the common parts and tools and accessories youll use on a car, its a huge investment but it also allows you to do custom fabrication, and repairs man parts modification that most guys only dream about doing.
going into the MILL purchase I had no reasonable or realistic expectation that the tooling to allow the mill to function correctly would require a great deal more accessory purchases than I expected, or what the cost of those accessories might be, this is and was MY fault of course for not researching the project further before the purchase was made.
the first thing I found was I needed bit chucks, collets and cutters and a coolant pump, plus a much better quality mill vise to hold material, all of which did not come with the basic MILL,.I don,t know how I could have been so unrealistic , I guess its mostly because every mill i ever used in college or a machine shop already had those accessories .
but if I had been realistic I should have realized that the tooling and accessories would easily add $800-$1500 more to have a functioning mill.
This slowed me down considerably but IT DID NOT MAKE ME REGRET THE MILL PURCHASE, AS ITS BEEN BOTH EDUCATIONAL AND AN ASSET TO THE SHOP.
once you have access to larger machine tools you obviously need to learn how to use them, below Ive posted some useful links and educational links.
you obviously need a good vise on the mill to hold material, a coolant pump to flow coolant to prevent burning up tooling and bits and the collets and end mills or other tooling to allow you to actually machine and drill metal.

yes I know this stuff is only of interest if you actually want to know how things get machined or if you own a milling machine, but it never hurts a darn thing to have the basic concepts down when some machine shop starts to B.S. you about the difficulty of doing some things, if you've got a good grasp on what you want done and how its accomplished you'll make smarted decisions.
the milling machine and the LATHE are the two real basic powered machine tools that allow most machine work to get done, add a decent welder and you can do a great deal of the work on your car or fabricate many custom parts

obviously youll want to shop for a good used mill because the cost can be pennies on the dollar compared to a new mill, but think thru your budget and goals and check the local bargain trader , magazines, Craigs, newspaper classifieds list etc.
keep in mind a MILL can do what a drill press can, but it can also do a great deal more

keep in mind its the tooling, the mill vise and cutters, cooling fluid pump and a bunch of smaller parts that make use of the mill functional, and all that adds up fast, so having a mills great, but youll have at least a couple thousand dollars in small parts and accessories and tooling, before your ready to build and fabricate custom parts, and the best mill in the worlds fairly useless without a precision vise large and solid enough to firmly hold the work and correct tooling to mill or drill the parts being fabricated

and every drill press or mill needs an adjustable vise

Well, theres little doubt stress levels effect my memory ,
I broke a small bracket on my welder cart,yesterday.
(so Im thinking, no big deal, thats easily repaired)
and I,m SO glad I purchased both my welders and a decent mill before I retired, because I sure could never afford those tools now... in fact I just for grins looked at the current cost of a similar mill and see the cost is at least 75% higher than it was back 10-15 years ago when I purchased most of my larger machine tools,
and after re-welding it, I placed the bracket that required machine work,in the mills vice, and I started looking for the appropriate mill bit to re-machine the bracket..

I looked for easily 30 minutes every place, in the shop I could think of. I could think of,no place I might have left a set of mill bits...I gave up and called a friend and asked to borrow a mill bit,of the correct type and size, which he was glad to lend, I got home, inserted the bit in the mill,and I finished the job which took only about 12-13 minutes, most of that time was used measuring and set-up time and then I pulled the mill bit, after I finished, oiled it down and placed it in a plastic zip-loc bag.
my friend was leaving on some short trip yesterday, as I borrowed the bit and asked me to return the bit the next day (today) rather than later that day.
well Im thinking where can I place the bit where I won,t forget to bring it with me,and they won,t get lost. and the obvious answer is in my car trunk or glove compartment so I walk outside , pop the car trunk and there in a large Tupperware box is all my missing mill bits, I suddenly remember I placed them in the trunk on top of the spare tire so I would have access to them when I went over to that same friends shop when we were fabricating custom accessory brackets for his race car a few weeks earlier.
like I said getting senile sucks!
