The SHO is a fun-to-drive vehicle. Although the ride is somewhat harsh, it handles well and has more than adequate power. Mileage is decent for a car with this much power. The interior is well-laid out and the controls are easy to reach. The car is well-optioned, and includes climate control, which is nice to have. My major concern is the poor camshaft design, which really ruined the owning experience of this vehicle for me. Also, they could have made sure that parts are more readily available. For example, the electronically-controlled suspension has unique, expensive struts. They would have been well- advised to update the V6 from the previous SHO's rather than go with a new V8.
The drivetrain is the strength of the car. Ride is comfortable on long trips. A ton of optional equipment. Sound system is one of the best I have heard in a stock auto.
Where Ford really messed up is the splined camshaft sprocket. When mine failed at 46K miles, it caused $2100 worth of damage and took 7 weeks to repair. Parts are hard to come by (struts), and repairs that are straight-forward on other cars are difficult on this one: the spark plugs took 4 hours!
