“my 1971 280SE 3.5 Cabriolet was my favorite of all time.”stevieboy1 · Oct 24, 2025 at 7:44 PM

• Coupe versus cabriolet: the value chasmmarket
  Commenters treat the open cars as a different asset class from the fixed-roof coupes, with the same basic body worth many times more as a factory cabriolet. This drives persistent talk of coupe-to-cabriolet conversions, which the community regards as inherently worth less than genuine cars. …
• 280SE 3.5 Cabriolet as the market pinnaclemarket
  The V8 3.5 Cabriolet is repeatedly described as rare (roughly 1232 built) and as the final year of hand-built two-door production, and it consistently clears $300k with sales reaching $346k, $357k, $380k and higher. Commenters maintain a running tally of the cars that have crossed the $300k threshold on BaT. …
• Six-cylinder versus 3.5 V8: is the V8 worth the premium?driving
  Enthusiasts split on whether the 3.5 V8 justifies paying two to three times the price of a six. Several long-term owners argue the lighter six-cylinder cars are more nimble, cheaper to run, and plenty quick, and that the electronic-injected V8 is fussy in traffic, while others accept the V8 commands more money. …
• A softening, buyer-friendly market in 2025market
  Multiple late threads describe desirable examples selling cheaply or going unsold, framed as a broader collector-car correction. Sellers and dealers note results well below recent comparables, while some commenters call it a buying opportunity. …
• Manual transmission rarity and disputed valuemarket
  Floor-shift four-speed cars are seen as unusual and desirable, especially in a 3.5, with one commenter citing total stick production of 122. Whether the manual actually adds money is disputed: some claim a large premium, others say it adds nothing on these cars unlike the W113 SL. …
• Rust and chassis solidity are the make-or-breakbuying
  Experienced buyers stress that the chassis, floors and structure matter far more than cosmetics because rust is what derails these projects. Salt-belt and Northeast cars draw particular caution, and bubbling around headlights and trunk seams is noted as a warning sign. …
• Original coupe bumpers are effectively unobtainablecosmetic
  Genuine W111 coupe and cabriolet bumpers are described as hideously expensive and virtually impossible to source, so many cars wear W108/W109 sedan bumpers as a cheaper substitute. Sharp-eyed commenters routinely flag these swaps, which knock the presentation and correctness of otherwise nice cars. …
• Rear hydropneumatic compensating springmechanical
  The rear axle hydropneumatic (nitrogen) compensating spring is a distinctive W111/W112 feature, and knowledgeable buyers want the original retained rather than swapped for a cheap aftermarket coil kit. The originals are no longer available new but are rebuildable, which commenters consider well worth doing. …
• Vacuum seat locks on the 3.5 Coupemechanical
  The 3.5 Coupe used vacuum-operated seat-back locks that release the seat when the engine is off; these frequently fail or get disconnected, and originals were often swapped for simpler 250SE manual-adjust seats. Owners describe practical fixes ranging from repairing a plugged vacuum line to substituting electric solenoids. …
• Air conditioning: dealer-installed and largely aftermarketownership
  Factory A/C was uncommon, especially on Euro cars; most systems were US dealer-installed under-dash units (Frigiking, Kuhlmeister, Behr). Owners note retrofitting R134a into the old R12 systems is possible but leak-prone, while adding a compressor is not especially difficult or expensive. …
• Restoration economics and the recommissioning mathownership
  Commenters repeatedly warn that these are expensive to bring to standard: full coupe restorations are pegged at a minimum of $50k and V8 project cars can reach $150k-$200k all-in. The recurring caution is that money invested can exceed the car's ceiling value, though targeted spend on interior and wood can pay back. …
• Wood trim and interior craftsmanshipcosmetic
  The hand-finished wood and leather interiors are a central part of the appeal, and refinishing tired wood (commenters cite Madera Concepts) is treated as high-return work. The atmosphere of the cabin is a repeated selling point. …
• Engine and gearbox swaps: divisive but sometimes excellentmechanical
  Several cars have received later Mercedes V8s (M117 4.5) or modern five/six-speed conversions to improve driveability and cruising RPM. Purists dock value for non-original drivetrains, but owners who have done it report dramatic improvements in refinement over the original four-speed automatic. …
• Engines and mechanical fuel injectionmechanical
  The inline-sixes (M127 220SE, M129 250SE, M130 280SE) are respected as strong, durable engines, with the 250/280 units gaining a six-plunger injection pump and a seven-main-bearing crank. The Bosch mechanical injection with its long intake runners is a talking point, and owners note the six-cylinder cars pull hard when revved. …
• Usability and driving characterdriving
  Owners consistently describe these as genuinely usable grand tourers you can drive effortlessly for hours and keep up with modern traffic, with a road feel that keeps the driver engaged rather than isolated. A commonly cited weak spot is a plastic shift-linkage bushing that fails. …
• Data cards, numbers-matching and provenance verificationbuying
  Buyers lean on Mercedes Classic Center data cards and stamped VIN/body numbers to confirm original paint code, transmission and engine, and note that A/C and other equipment was often added later. Missing data plates and unverified engines recur as points of scrutiny. …
