I bought new Honda Civic 15 months ago,i passed only 37 000 miles. Can i change this car?Can i bring back and get new from same dealership?

Yes, you will just have to pay off any loan you got on it. Then it is your car and you can trade it in.

You can certainly trade in the Civic for another automobile if there is not an outstanding lien on the vehicle. That's your choice. Go for it, if you can afford to do so.

Maybe?

If you now OWN the car, (free and clear) you are free to sell or trade it anytime you want. It might not be wise financially, but you are free to do it. You can do this at ANY car dealership, on any car you want to pay for.

If you are buying it on HP, then you don't own it yet. The loan has to be paid off before you can sell or trade it. Now if the loan is smaller than the value of the car, then this can be done, The dealer will pay off the loan, and use the leftover money as the deposit on a new car. Again, any dealer can do this. But chances are that unless you had a large deposit, or a short loan term the cars value will have dropped faster than the value of the loan. You will need to come up with some more $$ to be able to trade.

Either way, it's going to cost you a lot of money to trade after 15 months, because the first year of a cars life is when it drops in value the fastest.

Jeesh, you drove a LOT. 37,000 miles in 15 months is WAY above the national average.

You can certainly trade the car in, but you aren't going to get very much for it. I doubt that you would even get 1/3 of what you paid for it.
