INTRODUCTION
--------------------

These
very collectible cabriolets and coupes are referred to as 'Ponton' cars,
which has to do with the front suspension subframe design. When it first
came out, a German journalist likened to a pontoon or bridge spanning
the engine bay. (see photo)
More adventurous
in styling than the saloons, convertibles and coupes for this series
came with plenty of options including fitted luggage, two-tone paint,
a front bench seat and whitewall tires. These were among the last Mercedes
Benz which offered a manual transmission only.
HISTORY of the
220S & 220 SE Cabriolet & Coupe
The first
220S Cabriolet was introduced at the Frankfurt Auto Show in September
of 1955. The first production cabriolet rolled off the assembly line
in July of 1956. The coupes followed in October of 1956.
These cars
were very luxurious for their time. Of course the larger 300 series
cars were even more glamourous and exclusive. Mercedes Benz realized
that there was a market for a less expensive, more personal automobile.
This was achieved by shortening the chassis of the very successful 220
Sedan by 4.7 inches and adding lots of chrome, wood and leather. Still
hand-built, these elegant automobiles were very driveable. The platform
for these fine automobiles are very different from their sedan counterparts.
There are additional floor reinforcements to compensate for the abscence
of a roof, the overhang behind the rear wheel is longer. Longer doors
made for a very appealing look to the car and to save weight, the doors
were steel skimmed over alloy frames. Lower in weight, with better structural
strength than the previous model, the 220 was a better handling car
as well.
In 1959 the
cabriolets and coupes received the 2.2 liter fuel injected power plant
which gave them more power which they needed as they are very heavy
automobiles.
Produced until
November 1960 there were only 5371 Ponton coupe and cabriolets built
over the four years of production, making it a very rare automobile.
Mechanically
these coupes and cabriolets are identical to their sedan counterparts,
so mechanical parts are available. Some items are getting hard to find.
All
220's are fairly predictable. All will need water pumps and engine mounts.
Exhaust systems hang low and door locks can get worn, windshield wipers
are sluggish. Rust is a particular problem. (see diagrams below for
most common areas for rust problems.
These
are very rugged automobiles and will make a great addition as an occational
driver or even as a second full time driver. They are not very fast due
to the weight and low horsepower but they will run with traffic safely.
They were only
available with a four speed and a Hydrak clutch was available. The Hydrak
clutch was a innovative option.(see photo at left) The clutch would actuate
automatically as the driver moved the gear shift lever which would give
you two pedal control with manual shifting and no clutch pedal.
There were many
problems with the Hydrak so it became one of Mercedes Benz's less successful
options. Most Hydrak clutches have been converted to a regular clutch
system and a pedal installed.

Buying A 220S
& 220 SE Cabriolet & Coupe
Know what you're
buying and what to look for and know what to avoid.
When these cars are well
maintained and properly taken care of, they increase in value. Currently:(these
are approximate values based on actual sales of vehicles.)
-------------------------------------------------------------values
last updated SEPTEMBER/2016-
PLEASE
READ THIS FIRST!
A car's value is determined
by condition. Standard condition guidelines are as follows:
Excellent- A close
to perfect original or a very well restored vehicle. Generally a body-off
restoration, but a well done body-on restoration that has been fully
detailed may qualify. The vehicle is stunning to look at and any flaws
are trivial and not readily apparent. Everything works as new, all equipment
is original, NOS or excellent quality reproductions. PLEASE KEEP
IN MIND THAT # 1 CARS ARE VERY RARE, AND ARE ORIGINAL RIGHT DOWN TO
THE HOSE CLAMPS. DO NOT ASSUME THAT JUST BECAUSE A CAR HAS A #1 ASKING
PRICE, THAT IT IS IN # 1 CONDITION. MOST CARS FOR SALE OUT THERE ARE
LOW # 2 TO HIGH # 3 CARS.
Very Good- An extremely
presentable vehicle showing minimal wear, or a well restored vehicle.
Runs and drives smooth and tight. Needs no mechanical or cosmetic work.
All areas have been detailed. Beautiful to look at but clearly not a
# 1 vehicle.
Good- Presentable
inside and out with some signs of wear. Not detailed but clean. Body
should be straight and solid with no rust-through anywhere. Shiny, attractive
paint but may have evidence of minor fading or checking or other imperfections.
Runs and drives well but may need some minor mechanical or cosmetic
work. But it is useable and enjoyable as is.
Fair- Runs and drives
ok but needs work throughout the vehicle. Body shows signs of wear or
previous restoration work. Any rust should be minimal and not in any
structural areas. Cosmetics, body and mechanicals all need work to some
degree.
Poor- In need of complete
restoration, but is complete and not a rust bucket beyond repair. May
or may not run but is not roadworthy.
These values are from
Collector Car Market Review and are based on actual sales of vehicles,
not on asking prices of vehicles. Asking prices, and sales prices are
very different.

Keep
in mind that due to the high cost of restoration, mint examples of these
cars can and have sold for more than the prices quoted here.
When looking to buy one of
these great automobiles, make sure it is complete. Check the windshield
wipers and make sure they work. They are difficult to repair because
parts are intricate and hard to locate. Make sure all the chrome is
on the automobile. Chrome pieces for these coupes and cabriolets are
very costly.
Condition of a car CANNOT
be determined by its location. Don't be fooled by a car's current geographical
location. Just because a car is in California today, does not mean that
is where it started life.

Look at the car in general.
Walk around the car several times looking at the gaps for the doors,
trunk and hood. Look at the general overall condition of the car. As
stated earlier, rust is the main enemy of the coupes and cabriolets,
especially toward the rear of the automobiles. There is chrome trim
along the bottom edge, the metal under this trim gets very rusty. Also
around the wheel openings. Check the inner fender aprons and the mounting
flange for the front fenders also the inner fender leading edge of the
hood. Check the mounting area for the support arm on the rear under
the rear seat area. Check headlight buckets, turn signal mounting areas,
front fender edge around the door jamb. Check the quarter panel dogleg
area around the jack points. Look at the frame lower cover sections,
and lower firewall where the trunk attaches to the rear quarter panels.
Look at the lower trunk lid edge as well as the trunk floor. Also check
the spare tire well and the floor in the passenger compartment (especially
if the car has a sunroof.) The heat ducts on the car were made from
pressed cardboard, so they deteriorate. Fiberglass replacements are
available. These
cars are the simplest to restore. Their front end must be in top shape
for precise steering.
These pontons are great cars.
Very simple to maintain and fun to drive. The best tool to use for checking
the condition of body panels are your hands. The following illustrations
will show the most common rust areas.
 
Rust is the
major problem with these wonderful coupes and cabriolets. They are as
rust prone as the 190 SL. However, you can still buy all of the metal
parts for a 190SL, as they made 50,000 of them. So there are places
making reproduction parts for them. Unfortunately this is not so for
the Ponton's. All metal for them must be hand fabricated.
