pros
K5 GT-Line exterior design is fantastic with the aggressive front end, LED lighting and upgraded 18 inch wheels. The interior layout is roomy, seating is comfortable and the instrumentation with the LCD panel display is user-friendly. CarPlay works and sounds great on the speaker system. Drives and handles exceptionally well with good acceleration. All in all, a beautifully engineered car.
cons
Would be nice if it had the drop in phone charger!

pros
Great pickup, comfortable throughout. I like the color of the dashboard but it doesn't look like wood. I really like radio on screen in old time bulbs, but don't need cafe or fireplace on screen in my car. Hard to find phone on infotainment. Great price. Great panorama roof. I really like the new front grille and wheels. Power seats on both sides are great. Larger than Optima.
cons
Top end EX model: No wireless connection for phone but in lower models??? Built in charger is nice but bad location. Dashboard should have been digital. Cupholders are good but too close to dashboard -passenger has to reach over and it is difficult. Infotainment hard to understand. Why is gear change from eco to sport on the floor by seat controls? Hard to find while driving. In the trunk why did they take away interior handle? So now I have to touch exterior when closing trunk and handprints. Why did they take away sunglass holder on ceiling? Why no hybrid or leather seats? I liked gas button in car not locking gas cap. I liked little hiding spot on dashboard so not so messy. Optima had matte finish around doors so I could close without handprints.
