the only advantage the MUX has over the Sorento is it's height and is somewhat a dedicated off-road vehicle. Sorento's engine is more than enough at 197HP, no major issues based on the Sorento thread here. I got the 7 seater and didn't bother to wait for the "all new" one since I didn't like the specs on it, ride height is lower and ceiling height is lower than the current model. didn't like the new interior also.
