The purchase/trade-in of my 2001 Hyundai Sonata sedan 6 cylinder, that I had owned since new and was yet running very smoothly, for the new 2018 Hyundai Sonata was an all in all great experience disregarding any sentimental feelings. I really like the features of the new Sonata. The way it drives, the back-up map!!, all the electrical systems, the interior, the roomy trunk, the simplicity of operation that makes it easy for a senior citizen like me. I a glad I chose to stay with the Sonata.
