I have an 05 XLT premium so it's still pretty new to me. I can say is that it is the best all around vehile I have owned. A couple months ago, I stopped at a local dealer just for a test drive of a V8 07 ST. Man, what a difference. More power and A LOT better ride as far as smoothness, maneuvering and quiteness. I even liked the interior layout MUCh better than my 05, contrary to some who here who beg to differ. I did this out of curiosity, never intending on buying it (has a few free hours).
In the end...IMO, it was A LOT nicer than my 05 but there is NO WAY it was 1000's of $'s better than my 05.
So here I am with my 05, still enjoying the benfits of a SUT, all the while content. Until a completly different crossover with a bed comes along that is...
