Iam a proud owner of Kia Sorento EX - 2011 model and my car already done 6000km since April without any single trouble.
Yes it is good value for money if you want to keep it for over 3 years, it costed me QR103,000 (incl.insurance).
Now, the facts:
a.Kia offers 1 year or 21500km free service which ever comes first.
b. 5 years warranty on parts (incl.compressor) or 100,000km which ever comes first.
c. The periodic service cycle is 7500km and not 5000km as for other cars on road.

KIA is no more KIA that we knew earlier, the whole engine, body and chasis have been redone and it's got 4.5 rating out of 5 on international reviews.
Go for it my friend, you wont regret.
