So I finally got around to doing a Taurus test drive on all types of roads. Dealer did not have an SHO so I took out a limited. The engine performance seemed fine even out on the highway for getting up to speed and passing. Suspension was bit floaty, I would of liked it a little more refined but it was ok for highway and would be comfortable on long trips. In town and on winding roads not so great, allot of body roll. How much more refined is the suspension from a limited to an SHO without the PP? Although I initially wanted the PP I'm willing to go without as long as it's equipped with ACC for the long trips.
