You can, but don’t try to get a loan for it.
Banks are hesitant to lend money for a car without AC, for example. It dramatically lowers the reseal value. Yeah, you can still get a loan, but you will have a larger down payment and higher interest rate, unless your credit is so good that you don’t need a loan and could pay cash.
Almost all cars today have FWD and rack and pinion steering. You don’t want not to have power steering with this arrangement; it is pretty much a requirement.
Automatic transmission; yeah, they cost more, but a standard transmission severely limits the potential buyers. Sure, on some cars, standard transmissions are avaialble, and may even cost less, but that is not the majority or US vehicles.
Power windows, security systems, yeah, you can have them omitted, but it hurts the resale value, so why bother.
The cost of these systems is greatly reduced by making them standard. They increase the cost very little, but make it much easier to sell the car, either on the showroom floor or as a used car. If you were buying a fleet of cars, say for rental or company cars, then you can save some money by deleting some of these items, but otherwise, the sales commission is greater than the savings, meaning the salesman could very well throw those “extras” in for free to get the sale.
I knew a guy who has a car without security or remote locks or power windows. He curses his decision to buy the car, since these things are a PITA to deal without.
