In this meticulously well-documented example, you'll see that the Sigma had it going on as far as steering-wheel accessible controls. Though not actually mounted on the wheel itself, as has become the dominant layout, the Galant designers put all of the highest-use functions within a finger's reach, through the huge aperture of the one-spoke wheel. Most notable here is the turn-signal stalk, which protrudes out through the steering wheel, defying convention, logic and indeed, crashworthiness in a flourish that can only be described as "sort of French."
Do yourself a favor and spend a little time browsing this very large gallery of Mitsubishi Galant Sigma images. This very rare car is a time capsule from 1988 that is worth the price of admission. You can check out the auction (still days and days to go, eager bidders), here.
