I've had my Amanti 2006 model for 6 months now and I love it. The price is great also with great warranty. I had it serviced once with kia dealership and they took care of my issue promptly. I also get it confused very often for expensive rides. I have a jaguar parking ticket to prove it. Some of my friends make fun because it lookd like a mutt between a jaguar and a lexus.
Comfort, dual AC, fully reclining seats, nice bass, sunroof/moonroof, very very quiet, wood finish, leather interior, The looks of it. too many to display!.
Stronger engine, better shocks it inclines when breaking too hard, they should make the back seat to fully open, GPS option. Change the usual green color dashboard to white or blue (that'd be cool). That's all I can think of and I'm being picky. Just buy the 07 and it comes with most of these features.
