Buying a car through a dealer is legally better because bargaining is done through a company you trust and / or traditional, so all documents will be legalized and authenticated as legal (this is not always possible with private sellers). In addition, a dealer usually offers cars of origin and that probably will not give the owner a headache. After all, he has a reputation to watch out for, avoiding passing on cars with the potential for major problems.
Still regarding negotiations, it is worth noting that dealers always have partnerships with banks and other financial institutions that have financing. In many cases, there is even more than one financing option. Therefore, you avoid the bureaucracy of contacting the bank directly to finance your car.
