Really? Your current car is only worth about $2,000? It is normal to get about a $3,000 discount on a Niro without a trade in. That's ballpark what I got on my 2018 LX in January 2018 near the beginning of the model year. I'm not so sure this is a great deal, except for the dealer. As a business thing, might be worthwhile for you of course to cut out the hassle with both new car negotiation and getting a fair price for your well used car.
