Why it matters
The Twister Special is a Mach 1 built in a run of 96 for the Kansas City sales district only. It is regarded as one of the rarest Mach 1 variants, and RM Sotheby's rates it rarer than the California Special or High Country Special.
How rare is it?
Six separate kinds of rarity – never combined into one number.
Each kind of rarity is rated separately and never combined.
02Production & history

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
The cars grew out of a plan by American Raceways, which wanted 1970 Mach 1 pace cars for its tracks. When the company went bankrupt, Ford offered the design to the Kansas City sales district for its Total Performance Day on 7 November 1969. A detailing firm replaced the track logos with Mach 1 and Twister Special graphics. All 96 cars were built at Dearborn in October 1969 and numbered consecutively; Ford also made 90 Torino Cobra Twisters.
Ford ran short of 428 Super Cobra Jet engines, so 48 cars received that engine and 48 the 351 Cleveland 4V. About half had a C6 automatic and half a 4-speed manual. One extra test vehicle with a 428 SCJ was made for promotion.
