HISTORY
of the 190SL
-----------
The Road & Track October
1955 Test Said "The outstanding achievement of the 190SL is without
a doubt its quality in design and workmanship. But a close second is
the general feeling of solidity which it immediately conveys..."
Also known as "Baby Merc"
or the “Little Brother” to the 300 SL, 190 SL’s make a great and fun
collector automobile, and are relatively affordable. The car came as
a coupe (with a detachable hardtop) or a roadster with convertible top
to which a hardtop could be fitted. These cars were guaranteed to sell
to enthusiasts who couldn't stretch to a Gullwing and didn't need the
electrifying performance of a Gullwing. Although the 190SL shared the
same wheelbase as the 300SL, a number of it's major components came
from the 180 Saloon. Several modifications were made between the unveiling
of the prototype in New York at the New York Motor Show and the beginning
of production in the Spring of 1955. The first uni body Mercedes Benz
used a steel chassis with aluminum hood, trunk lid, doors and dash.
Even with those aluminum pieces, it was a heavy car, weighing in at
almost 2600 lbs!

Buying A 190SL
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. (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.
Once the mechanical parts
are sorted out, this is basically a bullet proof car. The only trouble
spots are the Solex carburetors and the old-fashioned T-50 power brake
boosters. The 190 SL’s are very rust prone so they must be checked thoroughly
at the following places: (see photos below for reference)
- all four jack points
- the mounts for the rear
trailing arms
- floors
- the spare tire well in the
trunk
- under the brake booster
and the battery tray
- the front fenders tend to
get rusty around the headlights
- the eyebrows above all four
wheels
- spaces behind the front
and rear wheels also tend to rust
Make sure the car you purchase
is complete. You do not want to buy a basket case, there are plenty
of these cars out there, so make sure it has complete sheetmetal.
Mechanical parts for this car are available, however, some of the
chrome plated items will cost you if you can find them. 190 SL’s are
a very simple car and therefore are easy and affordable to maintain.
To completely restore one can of course be a costly affair, but once
it is done, it is a very enjoyable automobile with lots of style.
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.
Where
to find the engine number and chassis number.
Check the VIN number. You
will find the VIN number on a plate on the right side firewall and
stamped on the frame near the voltage regulator. A small plate with
the same information is just above. The engine number is on a data
plate on the left side of the engine near the cylinder head.
The chassis prefix for
a 190 SL Coupe is 121 040. The engine prefix is 121 921.** |
The chassis prefix for
a 190 SL Roadster is 121 040. The engine prefix is 121 921.** |
** mid 1961 saw the
engine prefix change to 121 928 |
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. Ask
the current owner for all the documentation he has on the car. The more
information you have, the easier your purchase decision will be. The
best tool to use for checking the condition of body panels are your
hands.
RUST is of course
the enemy. 190 SL's were rust prone from the beginning and were never
adequately protected from the "monster that never sleeps". 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. Luckily the hood, trunklid
and doors are aluminum.
