Can i change my mind before sign the car contract, but I signed a handwritten paper said"I will buy the vehicle at OTD 21,500"?

I was going to buy a new 2016 sonata today. afger negotiation we agreed on OTD price $21,500. and then the dealer gave me a handwritten paper with only one sentence said" I will buy the vehicle at OTD21,500", I signed my name on it. and I also signed a auto loan application. However, the auto loan did't get approved because I'm a foreign student. Then I went home and found out a black friday $500 cashback program from hyundai which the dealer didn't mention at all during today's talk. So I'm wondering can I change my mind and renegotiate with the dealer to see if I can lower the OTD. I'm a little concerned about the handwritten paper, is that a legal document? I have NOT signed the final car contract. But I gave the dealer a certified check and also use my credit card as down payment. Can I just change my mind and back out? Thank you in advance for any advice.

asked & answered, You didn't like the answer so you are asking again ?

Its a very bad idea. Buy here pay here dealers are not set up to sell cars for cash. Their business is financing them.

You would probably get a lot more for your money from a private party. Or, if you could find a curbstoner that wasn't dishonest.

(That used to be me for a dozen years but Im retired now. I have no idea how you can determine if a local curber is honest or not)

The dealer associations would have you believe they are all dishonest crooks selling prior salvage cars without disclosure. While a few might do that, I sure as heck never did. I sold some rebuilt wrecks but always disclosed it.

The reason you might get a decent deal from a curbstoner is they lack overhead & employees. I was a one man operation.

I offered good deals for cash cars in the $1950-3495 range usually. Because I had no overhead other than vandalism and towing and no employees.

At buy here pay here lots, or car lot, you have the owner, the buyer /manager and the salesman all of whom want to be paid.

Shopping for a car for cash at a BHPH dealer is absurd. They are places of last resort for people with no other options who are wiling to pay 2-3 times a cars value for financing them.

All things being equal, a lower mileage car should have a longer remaining serviceable life.

However, all things are rarely equal.

How long a car lasts usually depends on how well it was taken car off.

But age can cause things to fail too.

I have had a low mileage car for the last 10 years and It needs something about once a year. Because its a 94 model. And because I don't drive much.

If I drove it more, it would need more frequent repairs.

High or low miles can affect a cars valuation by a lot.

The price difference between a very high and a low mileage car can be 50%.

Ive seen cars with less than 30,000 miles with bad motors and the warranty wouldn't pay for them because the owner never changed the oil. That's called abuse.

Ive bought cars with 200k miles where the oil was changed every 3000 miles with the original motor.

I didn't want a buick when I bought it. But it was half the price of a Honda that had twice the miles. I couldn't justify paying that much more for a higher mileage Honda.

Its not public record, in fact, its against the law to give that info out. Even if your vin was proper. And its not. Its fabricated.

A proper vin would bring up a number of places wanting to sell you carfax type info. You mistyped it.

There may be places that offer car history for less, but they may be scams. But none of them include the prior owners name or address.

Its not illegal to report a cars history. It is illegal to report the owners name or address and none of them provide it. You might bribe a DMV employee but what if its registered in a different state ?

I dunno much about cars, but I can make the choosing part easier. You've got 5 options. You try to reduce it to 2. Then it makes things easier.
You first figure out the one which doesnt deserve to fit on the list. Remove it at once.
Then from there its 4.
You can take your time to do more research/comparison and find whats the best car for you.
You do test drive for 4. Then talk to the owners and see which one fits you best.
You get more info if you interact with them in person. Online results are just 50%.

And then you can remove 2 more from the list.
When you get 2 choices to choose from, you can consider family/friends opinion and narrow down to 1.

Apart from the specs/looks, there is personal satisfaction and you reduce the cost of maintenance when you spend a month learning about each of them.
Goodluck
