Absoulutly excellent, in manual form. I tow a 2008 Ace Jubilee Courier (1500kg) with mine, towing limit is 1500kg. Tows great, but you will need to fit either spring assistor inserts of MAD replacement towing springs. I have the later, fantastic.
My father in law tows his bailey pageant monarch with a 54 plate Carens 2.0 crdi. No problems at all. Last year I fitted a pair of Grayston spring assistors to the rear just to beef it up a bit. Mpg and overall performance , he tells me is very good .
Kia are very serious cars and I have a Sorento. Excellent value for money.
