Just bought the 2011 Taurus Lim AWD with 303a pack,multi contour seats,adaptive cruise,and nav.Was a toss-up with the SHO but price and insur. cost played a factor. The 3.5 L engine has plenty of power for normal day use and uses regular gas. The SHO same motor but twin turbo jets out like a bullet and recommends prem.gas.. Both cars had same options inside except suade middle seat in sho lim leather,dash cosmetics diff color 20inch wheels to 19 inch on lim and steering slight diff in feel. I love the car but the choice was based on money cost and no need to speed but take both out for a ride and decide yourself.
