To clear up some SHO wagon stuff. Ford did make two factory SHO Wagons. They just took the engine/drivetrain, body kit , and interior and adapted it to an existing wagon. One was red and the other one was white. They were both 3.2/automatic cars. One of which featured the stock 16" slicer rims, and was the one tested by Car and Driver in April of 1993. The white one had 17" Corsa rims on it and was used to test the braking system of the 1994 Cobra brakes. You can read about them both here:

I personally think that white one looks kick ass, but I would have done like the green one and swapped in the 5-speed/3.0L combo. The green one on e-bay was like G said, wagon with the engine/transaxle, suspension, wheels, interior, body kit... everythign that differentiated SHO from sedan put on it. It is much easier to convert the wagon to an SHO than to convert the SHO to a wagon.
My fondness for station wagons started early in life. My parents bought a 1977 Dodge Aspen wagon with the 225 slant-6/3-speed auto when I was 6 months old. The car is still running, still in the family, still my mom's daily to-and-from work car. I drove it the first three years of college. It crossed 300,000 miles in my posession. I'll post a pic when i get home.
Many wagons come with a manual tranny.. just not here! My favorite two wagons in the world are the Volvo 850 R and the Audi RS4 Avant. The Volvo R came with a 5-speed in Canada and Europe only, automatic only in the states. The Audi RS4 Avant was basically an Audi 90 wagon body over top of a Porsche Carerra 4 drivetrain. It was probaby the most kick-ass wagon to date. It was only sold in England and South Africa.
But hey, the states you can order a BMW 540i Touring with a manaul.. 6-speed no less. OOOOH... there's an idea... M5 Touring.
Ok.. enough about wagons.
