Quite a lot of your hard earned money due to the spent X5 depreciation and the future Sorento depreciation!!!! But the 7 year warranty should offset that someway and give peace of mind.
I drove the new Sorento when it came out and the engine is very good compared to my older model. Ride and handling were improved too as was interior space etc. However it still did not drive like an X5 but few would expect that. Met some Sorento owners in Scotland recently and they were very pleased with the car's overall performance and economy. Yes they are lighter than the old model, but I would suspect that the better suspension makes up for that, and the tow weight is less than my older model, but who really needs to tow 3500kgs and that would mostly be in low ratio anyway. The noseweight of 85kg is less but is still more than adequate for a properly loaded outfit, and most caravan noseweights are limited to 100kg by the drawbar limit. The reason I did not go for the new Sorento is that its looks did not appeal and it had lost its genuine off -road abilty which I did use. Also when the new Sorento came out dealers were not keen to negotiate and it was getting expensive compared to its peers. So I went back to an estate.
