220SEb / 250SE / 280SE Cabriolets and Coupes 1961 - 1971
INTRODUCTION and HISTORY
This luxurious model was the last of the hand-built Mercedes. Only 13 cars per week rolled off the
production line. These cabriolets and coupes are true classics. Unlike other automobiles, these cars
were classics the day they rolled off the production line, and have remained so ever since.
The 220SEb was first introduced in 1961 and was considered to be an immediate success. Road & Track
magazine said "one of the best-looking body designs to come from any German concern." Exquisitely
proportioned and beautifully designed. Luxurious may very well be an understatement when describing
this model. There were no changes to the basic design until 1969. (Why mess with perfection, huh?)
Because of the high demand for convertibles, many coupes have been cut and converted into
convertibles, especially the 280 SE 3.5 coupes (as they are the most sought-after of the cabriolets.) SO
BE CAREFUL! This has been done so by unscrupulous people in the event of an unsuspecting customer
that comes to purchase a convertible. If you are looking at a convertible, make sure to check the chassis
number. If you are unsure of the car, call us with the chassis number and we will be happy to help verify
whether or not it is a true cabriolet. If you purchase a false convertible, it can cost you thousands of
dollars. Click here for information on what to avoid.
All of these coupes and convertibles are elegant, yet can still be driven and maintained with no fuss. The
later models with bigger engines are preferred, such as the 300 SE, (see separate page) which was rare
when it was new, and is a definite keeper now. The 280 SE 3.5 convertible is a definite collectible
because of it's power and grace, and also because of the grille, which is lower and wider. They are
elegantly trimmed out with leather and hard-wood veneer in the dash.

Buying A 220 SEb/250 SE/280 SE
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.
PLEASE READ THIS FIRST!
A car's value is determined by condition. Standard condition guidelines are as follows:
Excellent- As 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. 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 for one of these cars, condition is everything. These cars are large, and a complete
restoration will become a costly affair. Watch out for rust spots, (SEE PHOTOS BELOW) such as in the
headlight buckets, the edges of the wheelwells and in the doors and rockerpanels. Trim condition is
important because replacement pieces are hard to find. Bumpers can be fixed and replated if they are
dented, but must be replaced if they are rusty. Convertibles are usually in rougher shape than coupes
because of sun and water damage to the top and leather interior. The 220 through 280 coupes and
cabriolets engines are based on the sedans, therefore, mechanical parts for these cars are in no
shortage.

These cars can be found as excellent originals, and they are worth looking for. You can save money on your
restoration if you purchase an automobile that is in fair to good condition. 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.
Where to find the engine number and chassis number: You will find the body plate on the radiator core support.
This plate will give useful information if you know how to "decode" it. This was the factory's "build plate" it gives
the color code, and option codes to which the car was built. DO NOT confuse the numbers on this plate with the
VIN number (or chassis number)of the car. VIN number is stamped on the right front frame rail. Also stamped on
the radiator core support. Later models (after 1968) have a plate pop riveted to the windhield pillar post and a
data plate on the inside door. But because these plates can be removed, and/or replaced, always check the one
stamped into the right front frame rail. Use
the illustration for location of plates

ALWAYS put your intended purchase on a lift, up in the air to fully inspect (and poke if necessary) the
bottom undercarriage of the car. Any owner who won't allow this may have something to hide.
The best tool to use for checking the condition of body panels are your hands. The following illustration
will show the most common rust areas.
Oil leakages: all older Mercedes have some small oil leakages.
Valve guides, valve stem seals, play in piston ring. An exhaust oil cloud after strong acceleration points to
defective valve stem seals or valve guides – play in or worn large piston ring are frequently also a cause.
Fuel pipes may be porous.
Transmission weaknesses – pay attention to wear
Additionally the chassis may have the following weaknesses:
Rubber seals : Aged by drying-out or dissolved by engine oil, which is distributed by the wind over the
chassis bottom.
Tie rods: may be worn
Steering damper: may be worn, and not work correctly
Brake hoses: Ageing - the brake hoses fill-up from the inside, reducing the passage, life span is 15 years
(manufacturing date is imprinted)
Water hoses
