The Fintail — Heckflosse in German — is the upright Mercedes of the 1960s with small tailfins and a formal greenhouse. The family is usually discussed as W110, W111, and W112, built from 1959 into 1968 depending on type. W110 covers the four-cylinder cars many people actually find for sale (190c, 200, 190Dc, 200D and their kin). W111 covers the six-cylinder sedans such as the 220b / 220Sb / 220SEb. W112 is the more exclusive 300SE line, with extra brightwork and, on many cars, air suspension and more elaborate finish. The two-door W111s are a separate, more expensive conversation on the coupe page.
I like these cars because they still look like Mercedes when they sit at a curb, and because a well-sorted six can be a pleasant, upright tourer. I am cautious because they are now six decades old, and the fins do not keep water out of the rockers.
Which Fintail you are actually shopping
Four-cylinder petrol and diesel W110s are the volume cars. They are simpler and were built in larger numbers, which helps with some mechanical pieces and does not help with rust. Six-cylinder W111 sedans have more grace on a highway. W112 300SE cars sit higher in originality conversations; air suspension, when fitted, is a specialist system you should test rather than admire from across a field.
US-market cars, European cars, and later grey-market arrivals do not all wear the same bumpers, lighting, or emissions equipment. I identify the type plate and the engine before I talk about “a typical Fintail.” A diesel 190Dc is not a 220SEb with different badges, and it should not be priced as one.
Rust and structure
Sills and jack points, floors, front and rear arches, the spare well, and door bottoms are the usual list, because water and mud have had a long time to work. Fintails also suffer in places related to their specific panels: around headlight visors and brightwork, at the base of screens if seals have failed, and in trunk gutters. I look at jack receivers with particular care because a failed lift point is how these cars get damaged during the very inspection that was supposed to save them.
A small inspection light inside the front wheel arch, with the wheel turned out, shows scale that a listing photo taken at ten yards will not. Undercoating that looks younger than the car is a prompt to ask what it covers. The order of operations is the same humility I apply to later cars in the W123 rust article, even though the panels differ — structure first, paint last.
Compared with a Ponton, you often get slightly more usable parts support and a more modern driving position, but you do not get immunity. Compared with a W108, you get a more upright cabin and, usually, a lower ticket if the car is a volume W110 or W111 sedan rather than a W112.
Mechanical watches
Cooling systems of this age leak, clog, and run hot if the viscous clutch or the radiator has given up. I want to see stable temperature on a drive that includes idle. Brakes may still be drums at some corners depending on type and market; they should feel even and trustworthy, not merely nostalgic. Steering play that you can measure with your fingertips at the wheel rim needs a number, not a shrug, before you drive the car in modern traffic.
Fuel systems vary: carburetors on many cars, mechanical injection on certain SE models. Each has specialists. I do not assume a general repair shop that is excellent on W123 diesels is automatically fluent in a 220SEb injection setup. Ask who works on this exact type in your area before you fall in love with a color.
Diesels of the W110 series are slow by any modern standard and charming if that is what you wanted. They share the broader Mercedes diesel culture of glow plugs and patience. Gasoline sixes are the ones I point highway commuters toward, provided the car has been maintained as a six, not stored as a sculpture.
Air suspension on a W112 (and the later related idea on W109 cars, which are not Fintails) must be demonstrated: height, leaks, compressor behavior. A car sitting on its stops “because it has been parked” is a car whose system you have not seen work. For how air suspension is discussed on the later S-Class cousins, see the W108/W109 guide; do not swap parts assumptions between a W112 and a W109 without checking.
What they are worth, spoken loosely
Nice Fintail sedans generally trail the money paid for top W111 coupes and cabriolets, and they have risen from the days when they were simply old taxis in some markets. I will not invent a median for 2026. Sold results for the same type — W110 diesel versus W111 220SEb versus W112 — are the only comparisons that matter. Projects should be priced from welding quotes backward, not from a fantasy of what the fins will look like after a $900 paint special.
Original interior patterns and complete brightwork help. So does a documented engine that matches the type. Modifications — disc-brake upgrades, later electrical tweaks — should be disclosed and priced against other modified cars. There is a path to a pleasant driver and a path to a show restoration; they do not share a budget.
Questions about buying a Fintail
- Can I daily one? Possible when the car is fully sorted and your roads are kind. Parts patience is required. Many owners treat them as fair-weather tourers.
- Fintail or Ponton? The Fintail is later and often more usable on a modern road. The Ponton is an older restoration puzzle. Drive both; read the Ponton page if that shape is what you actually want.
- Is a W112 too complicated? The air suspension and the extra finish are extra systems to maintain. Beautiful when healthy. Expensive when assumed to “just need a compressor.”
- What about rust I can “see later”? If you can see it in a photo, it is already later. Budget the repair now or walk.
