The car is at 40k miles now. Only ever had oil coolers every 6k miles and two small recalls that took hours to fix when I brought it in. I pounded it the first year I had it, put on 20k miles that year and averaged 44 MPG all highway.
Kia rates their products just like these manufacturers - separate from the vehicle - so in this case it appears the Sorento factory hitch is not rated as high as the aftermarket hitch. As long as your trailer's loaded tongue weight doesn't exceed lbs and the total weight of the loaded trailer doesn't exceed lbs, you will be within your capacities.
The car is Spice Red with black leather interior.
Both the paint and body are in great shape as you can see in the pics.
