What exactly are the benefits buying a car through the stealership? Buying from a private seller gives you no taxes and if the seller tries to bullshit you, simply walk away. Try going into a dealership they will attempt to legally hold you hostage as long as they can. Other than buying a new car I don't see the draw of a dealership.

Some people want brand new cars straight from the manufacturer.

Some people are idiots.

The only advantage I see are lemon laws that mean if it blows up before x miles then you get a refund, although in a lot of places that only applies to new cars

Usually financing

I could see this if you had bad credit but a bank usually gives better rates than a dealership.

Do dealerships even offer good financing rates?

Not really, but for those determined to purchase a car they can't afford, it's better than no financing.

I financed my car at 0% off the lot with it being under a year old, so I guess its possible.
... It was an econobox, though, and it was near the end of the year so they may have just wanted to make room and get rid of the car.

Girls at my college buy new expensive underwear, carefully use them once or twice. They return the used underwear with some creative story, the tags still attached to the garments, for full credit. The underwear goes back on the hangers, ready for the next customer.

Some people have this concern about buying a new car, because they don't want something that other people have used. Well, unless you follow your your newly manufactured car from the assembly line and QA and customer-prep, you really don't know who has already driven your car and what they did with it. Yeah, the floor mats are still covered in plastic, that's all you know.

Dealers dont offer financing
They work with 3rd party financing companies
