Does anyone have good sources/stories to verify the safety of a W123? I've got a 1977 300D, I know it doesn't have airbags, but still is an extremely solid car with crumple zones. Some people are questioning the safety of it, so I was wondering if anyone had some sources or ways to prove it's safety. Pros as well as cons are welcome.

Its safer than the average 1970s car but I wouldn't want to have an accident in it vs a modern car. Besides airbags it lacks, ABS, seatbelt pretensioners, UHSS structure... the list is long. That seatbelt alone are not going to prevent your head from impacting the steering wheel.

I saw this advertisement the first time in a theater as part of a "best ads from around the world" film festival. You could have heard a mouse hiccup when it was over. The impact of the footage when seen on a fullsize movie screen was incredible.

W123 Crash - Mercedes-Benz Forum

If the link doesn't work, google "Chapmans Peak directed by Keith Rose".

Based on an actual event.

New cars have piles of safety technology that is designed to allow them to do well in crash tests. Real world collisions do not necessarily match controlled crash tests.

Having been through a severe side impact in a w126, where I sustained a serious concussion, the only thing I might wish for would be side airbags, but not even all modern cars had them standard until quite recently.

“Let's take a drive into the middle of nowhere with a packet of Marlboro lights and talk about our lives.” ― Joseph Heller, Catch-22

In a crash test, what is the chance of a crash?

In the real world, one has to consider other factors. Like the chance of getting into a crash in the first place. I wonder how the relative poor performance of the typical diesel W123 comes into play there. I have had a few close calls that would not have been so close in a car with a bit more get up and go.

Anyway, when watching that video, all I could think was "Step on the right rudder pedal."

I think there is a wealth of false info and misunderstanding about auto safety. Few remember that the federal mandate was either air bags OR an automated seat belt. The primary purpose of a front air bag is to protect unbelted occupants. Ditto for padded dashboards (~1964?) and collapsing steering columns (~1968). Better for society that unbelted drivers die quick and not reproduce. Re seat belts, my 85 300D has self-tensioners. It also has a stupid "gravity lock" with little ball that likes to get stuck and make it so I can't fully pull out the seat-belt and use it until it decides to reset sometimes a day later (safer?). All the above is only to protect a driver who runs into things. I never have in 40 yrs of driving. I never follow too close, change lanes without turning my head to look and signaling, or speed on wet roads. I have been hit multiple times in the rear and sides by idiots, usually with no insurance. I feel safer in my 300D in a side collision than most new sedans, but safest of all in my 65 Newport with its wide heavy doors and really long "crush zone" trunk. That is where the idiots usually attack.

The front disk brake mandate (~1973) was to minimize people going off mountain roads from losing their brakes after riding them miles downhill - think Florida drivers on the Blue Ridge Pkwy.

An amusing youtube video is from the Insurance Institute (or such) claiming to show how much safer newer cars are by a partial head-on crash of a modern sedan against a ~62 full-size GM sedan. The newer car slices thru the old car, leaving a cloud of rust dust. I am guessing the old full-frame car had totally rusted frame rails and body, and maybe some missing parts. What happened to the "crumple zones" idea in the new car, which came thru almost unscathed? That video has many classic car owners saying their cars are unsafe.

I remember seeing a CL ad for a 300td parts car, I asked the guy what happen. He said he hit the back of a flat bed trunk and went over a cliff on Hwy 1 in marin county.....both him and his dog walked away....

I hit a guard rail at 60mph in Cali....I broke a head light and put a dent in the fender..

I feel totally safe in my car and I am never worried about not walking away from a crash.

In a newer car, I would get pinned to the dash in an accident and most likely would not be able to open my door....

The words you're looking for is "a false sense of security".

Yes, you are definitely guessing when you talk about this video.

Even if the 1959 Bel Air was brand new, I'll take my chances in the car designed around seat belts, air bags, a safety cage and crumple zones, thank you very much.

An even better example of how quickly the technology has evolved.

But hey, don't let that change your dogmas. I'm sure a car that was never crash tested during its development 60 years ago is way safer than anything designed and repeatedly crash tested today.

Much safer in a crash than a motorcycle. Beyond that I can't say for sure. I did get rearended by a 1/2 ton Chevy pickup last year. His junk left on a flatbed. I drove mine home.

Who(m) is questioning it's safety - and what is their reason in questioning it? i.e., what's their end game......

Skip, why are you comparing it to "a motorcycle" when it's a car? Sounds like apples and elephants again......

It was safer than any other car on the road when it was new and for some years to come thereafter, except for an S-Class Benz. People who tell you it's an unsafe car are idiots.

A lot of drivvle is written about modern cars being safer because of ABS, better handling etc so you can "avoid' the accident. That may be so in some circumstances. But you can be involved in an accident when sitting stationary at a traffic light and some dumbass runs a red light when all the gizmology in the world wont save you. The only thing that matters in that case is the strength and design of the vehicle you are sitting in.

Almost fifty years after the W123 debuted it's possible that if you buy a new car you might emerge from an impact better off than if you were in a W123 but In my opinion you're as better off or better off in a W123 than many if not most of the average cars built over the last fifty years.

Regarding the advert of the Chapmans peak crash. I recall seeing that when I was a youngun back in SA. BMW immediately countered with a really weak ad claiming that if he'd been in a BMW he wouldn't have left fallen asleep at the wheel and gone over the edge in the first place. It was a pathetic attempt at a riposte and they dropped it pretty quickly as I recall.

Interestingly nobody ever tried duplicating that feat in a Five series BMW...

However that is not the last time a W123 saved it's owners life in that manner. Some years later a similar incident occurred in Lesotho. A landlocked mountainous kingdom completely surrounded by South Africa. A 123 owner survived a similar plunge down a mountain cliff side. And Mercedes Benz also used that incident in an ad campaign. Interestingly enough BMW didn't even attempt to counter that one.

With the Chapmans peak incident (A road I have traveled on a few times myself by the way) MBSA gave the guy involved a new Mercedes. But the next time it happened, in Lesotho, they did not, much to the chagrin of the owner. Perhaps they were worried they might have to keep dishing out new Mercedes if the owners kept surviving apparently unsurvivable accidents

They're both vehicles. Every time I go somewhere I have a choice of a W123 or a sport bike. Statistically, motorcycles are the most dangerous means of transportation. If, like me, you're willing to ride one, then pretty much any car is an improvement in terms of safety.

I feel safe in one. As mentioned above, a side airbag is all I'd want for it.
