Yes.
Step 1. Find a person that wants bitcoin AND has a car that they are willing to exchange to get bitcoin.
Step 2. Offer that person bitcoin in exchange for the car.
Step 3. Negotiate an amount of bitcoin to be exchanged that is agreeable to both you and them.
Step 4. Exchange bitcoin for the car.
i already told in my post that i want to buy a car without exchange my bitcoin.
If you aren't willing to give them your bitcoin, and you aren't willing to give them your fiat, then why should they give you the car? Are you looking for a FREE car? I thought you said you wanted to BUY a car. That implies that you are going to give them something of value in exchange for the car that they give you.
i think you do not read my post properly bitcoin exchange mean convert your bitcoin to Fiat and i am just want to buy a car with bitcoin. not with fiat
By saying: Exchange bitcoin for the car, he means you will trade your bitcoin for the car.
Exchange: the act of giving something to someone and them giving you something else.
And this what you have to do. Just found someone who is willing to sell a car for bitcoins, and do the trade.
