You can buy a car with cash but you will need extra documents to prove the cash is obtained legally, otherwise you can. Happens all the time actually in my country at least, so I am unsure where is your information coming from. It is less convenient than the bank transfer and takes extra paperwork but possible. Also of course you can go to used car market or buy from ads from a private individual, most of them will refuse cash tho. Nothing of it is anonymous of course.
