Standard & Optional Equipment
Standard Equipment

Except for some early 1989 models, every SHO came from the factory with some standard features you might consider luxurious compared to other family sedans of its era (and even today!). The "extended range" options package for non-SHO Tauruses was standard.
You couldn't find a Taurus SHO without the following equipment. Features include: half cloth/half leather seats, an 8 way power drivers seat, 4 wheel disc brakes, climate control system, power mirrors, windows, and locks, Ford Premium Audio sound system, 15 inch "basket weave" wheels ('89 and '90), followed by 16 inch "slicers" ('91 and up), an "extended range" 18 gallon fuel tank (although some SHOs came with the SLO 16 gallon tank when supplies were low).
Some model year Gen Is and all Gen II SHO Tauruses came standard with ABS and a drivers side airbag. Later model Gen II SHOs ('93 and up?) came standard with VAPs (variable assist power steering - power steering boost varies with speed). VAPS may sound like fun, but many SHOtimers disable the feature (see Adjusting the Vaps) because it seems to increase or decrease the power steering boost a little too suddenly during high performance driving.

The 212A package
 1990: Moonroof, leather upholstery, 8-way drivers and pass seat, electronic a/c, jbl system.

The 211A package 
The 211A option package was popular on many early SHOs - it's reproduced here for those looking to see if they have the 211A.
