 If upgrading to the Harmon Kardon stereo system, you sacrifice a CD player. The sacrifice is worth it. You can use a personal Apple IPhone, Apple or other brand Ipad as well as an MP3 to play your recorded music with the USB cord. Other than this perhaps negative for some buyers, it is a delightful ride with all the top safety features and luxurious features of the finest cars offered by all top auto manufacturers and surpassing them. It should be noted that this is my second newly purchased KIA. The previously owned 2010 KIA Forte LX accumulated over 195,000 miles with only normally scheduled maintenance. BRAVO! I expect no less than the attainment of this achievement for my 2016 KIA Optima SXL Turbo when combined with the past exceptional KIA service.The Kia Optima has acquired another ten thousand plus miles on it and I am just as pleased as in the initial review of ownership. In three thousand the dealership pointed out that the front tires will require replacement; the softer rubber of the Michelins wear faster than normal and Kia will no longer use these tires. Two minor recalls were repaired last week, the transmission paused when removing the foot from the accelerator pedal and the track of the moon roof required lubricating. Total cost for maintenance to this date has been $39.00 for an oil change.
