“The M189 is a magical engine… a true joy at high speed.”jaimekop · May 17, 2018 at 12:17 PM

• Air suspension: the Achilles heel, servicing, and specialistsmechanical
  The self-leveling air suspension is universally cited as the W112's defining vulnerability: cars sink over days to months when the front main valve or bellows leak, and correct repair demands rare valves and expert knowledge. Commenters point to bellows/struts being available and comparatively affordable, but leveling valves are 'unobtainium' and specialists (Star Motors / Neil Dubey, Martin Werminghausen at 600airsuspension.com) are the known fix. …
• The M189 alloy inline-six and its Gullwing lineagemechanical
  The 3.0L all-aluminum M189 with Bosch mechanical fuel injection is revered as a direct relative of the 300SL Gullwing motor and praised as a joy at speed, but it is repeatedly called hard to work on and difficult to find parts and experienced mechanics for. It is prized as a rare aluminum-block six, distinct from the later V8s that replaced it. …
• Restoration cost and parts scarcity: the open-ended checkbookownership
  Owners and dealers repeatedly warn that restoring a W112 is far more expensive than buying a sorted one, with anecdotal figures from a $113,000 restoration receipt to guesses of $100,000-plus and a rule of thumb to triple a project's purchase price. Small parts such as the correct distributor cap are described as unobtainium but rebuildable. …
• Rarity and production numbershistory
  Commenters consistently cite roughly 2,419 W112 coupes built 1962-67, with the four-speed manual far rarer since automatic was standard, and only a few hundred cabriolets (with a claim of 708 cabriolets total and just 54 in 1967). One collector notes only 22 W112s had ever been listed on BaT, twelve of them coupes, underscoring how seldom they trade. …
• Market: undervalued coupes and sedans versus six-figure cabrioletsmarket
  The community broadly views pillarless coupes and sedans as undervalued and finally rising, with several sales framed as bargains and cars trading for less than a mid-range new Benz. Cabriolets are a different tier: a 1966 cabriolet sold for $280,000, and an owner of another insists a good one should be a $200,000-$300,000 insured car, even as some cabriolets still fell short of reserve. …
• Body-style hierarchy and W112 versus W111market
  Enthusiasts rank the W112 as meaningfully more car than the W111 220SE/250SE, calling the difference monumental, and several argue the 300SE coupe is the one to have over the later 280SE 3.5 because it is the only coupe with air suspension. The four-door sedan is considered the rarest survivor, with commenters noting almost none have appeared at auction. …
• Extra chrome and brightwork as the W112 signaturecosmetic
  The additional chrome side trim and wheel-arch moldings are seen as the W112's visual identity, described as jewelry that signals its exclusivity over the W111. Purists object when that brightwork is added to a W111 to imitate a 300SE, and a missing wheel-arch trim is repeatedly flagged as a fault on 300SE cars. …
• Wood binnacle, leather, and interior craftsmanshipcosmetic
  The full wood instrument binnacle is singled out as a work of art and a defining W112 feature, alongside hand-finished wood trim and original leather whose character owners say cannot be duplicated. The veneer on the binnacle is a known trouble spot, prone to lifting and needing refinishing. …
• Air conditioning: dealer-added, and the no-AC discountbuying
  Air conditioning on US cars is widely described as a dealer-added Kuhlmeister system rather than factory equipment, and its absence is repeatedly named as a reason buyers stayed away, especially in hot climates. Several commenters note AC can be retrofitted to look original if all the correct parts, including a different fan clutch, are sourced. …
• Rust vulnerability and where to inspectbuying
  Rust is treated as the big money pit on these Mercedes, capable of devouring thousands in bodywork, so no-rust survivors from dry climates command real premiums. Commenters flag specific trouble spots including the spare-tire wells in the trunk and clogged sunroof drains that corrode the rear quarters. …
• Engine swaps: 6.3 and V8 restomodsdriving
  A recurring subculture swaps larger Mercedes V8s (6.3, 4.5 M117) into 300SE coupes and cabriolets, one described as scary fast and tail happy and another as the ultimate Q-ship convertible. Purists push back hard, arguing a stock 300SE coupe is already perfect and the modest power gain does not justify altering it; the M189 pedigree ties directly to the 300SEL 6.3 from which AMG grew. …
• Autobahn cruiser character and the air-suspension ridedriving
  Owners describe the W112 as a serene high-speed cruiser designed to run flat-out all day without stress, comfortable and quiet at 70-90 mph, with a build quality commenters say is unattainable in modern cars. The air suspension shapes the ride profoundly: at full height it can feel harsh, while in the low setting the road disappears, and a neglected system ruins the experience. …
