Recently, I was in Austria as part of a group of Canadian auto journalists invited to the launch of the 2009 Mercedes-Benz CLS and CL-Class coupes. As well as giving us the chance to drive these new models, the world’s oldest carmaker also treated us to what it called “a history of coupes.”

From its vast museum collection in Stuttgart, Germany, Mercedes-Benz brought models from each preceding generation of coupes, going back to 1955, and parked them at our test centre on the banks of the Danube.

There was a 1969 280 SE 3.5, a 1972 250 C and a 1992 230 CE, but the one that caught my fancy was a 1955 300 S. Its heritage goes back to 1951, when the first of its generation was exhibited at the Frankfurt motor show.

By American design standards of the day, when tailfins were beginning to be all the rage, the 300 S looks like something left over from the 1930s. Compared to the now iconic 1955 Chevrolet and Virgil Exner’s “Forward Look” Chryslers of that year, the 300 S is a little on the stodgy side. But that’s what makes its lines so classic today, with its long hood, short deck, separate fenders and upright radiator shell. Under the hood, however, it was quite advanced with direct fuel injection – something that wouldn’t be the norm on American cars until the 1980s.

It’s also a true coupe, with a rudimentary rear seat for occasional use only, and there’s enough real wood trim on the dash and door sills to supply the needs of a dozen or so 2009 CLS 550s.

One of my younger colleagues read the specs for the 300 S with scorn because its 2996-cc inline-six was capable of producing only 175 hp, its top speed was 112 mph and it could accelerate from 0-60 in 14 seconds.

I tried to tell him that back then, that was more than respectable performance but I don’t think he was listening.

By comparison, a 1955 Mercury Montclair convertible, powered by an overhead valve, 292 cubic inch V8, produced 198 hp and was clocked from 0-60 mph in 12.8 seconds by Mechanix Illustrated’s legendary auto reviewer “Uncle Tom” McCahill.

Today, according to the Mannheim Gold Book, a 300 S Coupe is worth anywhere from $90,000 in “fair” shape to $190,000 in “show” condition. The Montclair ragtop? From $16,000 to $93,500.

With a 0-100 km/h time of 4.5 seconds and 250 km/h top speed, the 2009 CLS 63 AMG would blow the doors off that venerable 300 S. But in 47 years will anyone be able to repair or replace its vast array of electronic components? The 300 S will be 100 years old then, and still on the road because of its relative mechanical simplicity.

Some things really are built to last.
