I know all Fords are not created equally but my SHO had 7500 miles on it when I bought it from the dealer and it currently has 74,000 on it. My only real problem was the cam shaft but nothing else other than normal maintenance. It is one of the best all round cars I've ever owned. Excellent comfort, outstanding performance, superb handling (NO oversteer!) and all the creature comfort features you could ask for. No tranny problems for me.
The SHO has great handling especially when pushed hard in turns. The vehicle loves highway driving. You can feel the effect of the aerodynamics at 80 mph.
There should have been a recall on the overhead cam problems. Other than that if Ford could improve on consistent quality & gas mileage it could be the best car they ever produced.
