I've been really disappointed with Kia, I've recently purchased a Kia ceed and have had issues with it and the dealer, the road noise and interior rattles is horrendous and our Audi although 10 years older is nicer.
With the issues and the car going back I've had courtesy cars from them and had a brand new Kia ceed, and our 18 year old Audi was still nicer, granted it had more room than our Audi, but the road noise was worse, the interior quality was not as good could really notice some of the corners cut to keep the price low, the steering and feedback through the wheel was really vague and off putting with how light it felt.
I've not driven the rest of the range so couldn't comment on others, but with the disappointment of the brand new ceed, it's really put me off the others.
