Most W110 sedans in this data trade affordably, from roughly $4k into the low-$20ks, with commenters framing them as bargains against modern cars. The extreme outlier is the coachbuilt Universal (Binz) wagon at $51,000, repeatedly called a 'unicorn,' underscoring that body style and rarity, not the base sedans, drive the top of the market.
