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.) Currently:----------------------------------------------------------------------------------------------------------------------------------- values last updated Dec 07 The following values represent vehicles in # 4, #2-3 and #1 condition

• Very bad cars which require major restoration will cost around $14,000.00
• Good cars, driveable and reasonably well maintained, cost around $28,000.00
• A mint example, with low mileage can cost $47,000.00

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.

A car's value is determined by condition. Standard condition guidelines are as follows:

1. 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. **Understand that perfect cars are VERY RARE
2. 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.
3. 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.
4. 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.
5. 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.

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)

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.

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.

Look for rust in the following places.
