Just bought a Sorento 2 weeks ago and so far no regrets. I got the 2.2 Si in manual.
I took it for a test tow with my 2 tonne caravan and it is fantastic! Wanted to get auto but towing capacity was only 2 tonnes so I bought the manual with a 2.5 tonne towing capacity.
I have 3 kids and they have nothing bad to say about this car, I travel at 110km on the freeway with caravan, it's very impressive! People TRY to overtake just to see what was powering it.
My wife was hesitant when I decided on the Kia, but all her worries are now gone. If anyone is in the market for a powerful and efficient tow vehicle check out the Sorento! You'll be pleasently surprised!
