1991 Mercedes-Benz 350-Class Sedan 350SD Turbodiesel 4dr Sedan


Review

This is a rare car. The steal in the 1991 350 SD is different than all the rest of the lineup that year being lighter gauge but higher strength to make the 350SD lighter and it was. If you have an original engine, it's a time bomb. It will happen, the bent rod issue. I had three bent rods in my "original" engine. Top speed speedometer indicated is 112 MPH with the bent rods and the engine needing a lot of oil all the time. I put a new long block in and turbo with the updated connecting rods and the oil consumption is normal now. Also the top speed is still 112 MPH. I was able to adjust the turbo boost pressure to 1.0 bar and this helped acceleration.

Review

My father-in-law bought the car new and treated it like his baby. He became ill and gave me the car a few years ago. After 6 months of getting the car acclimated to the road again, I have had zero problems. It starts easily in all weather and is an absolute pleasure to drive. On the highway, it cruises effortlessly. I concur with the cup holder comment. The headlights could also be brighter. However, that being said, I love the car and expect it to last for many, many years.


Best Features

Design, comfort, ride, reliability.


Worst Features

cup holder; brighter headlights.

Review

Only had the the car for a year but virtually no problems mechanically speaking. Gets amazing mileage for a brick on wheels (low to mid 30's normally), driving in snow and ice with so much torque in the rear end takes some getting used to but its for your own good. Honestly when they say they don't build them like they used to this is the perfect example.


Best Features

Grabs attention, Great mileage, massive amounts of leg room, large trunk.


Worst Features

Honestly none but a modern V8 twin turbo diesel that can have a programmer plugged in would make for a great new rendition of this car.

1991 Mercedes-Benz 350-Class Sedan 350SD Turbodiesel 4dr Sedan


Review

As the 3rd owner, I have been pleased with overall performance and fuel economy of this model. Original engine is doing well, regardless of bad reviews, now has 188K. Ownership of an aging diesel Benz is not for the feint of heart, and I am fortunate to have a foreign car mechanic who knows this baby inside and out. I get OEM parts through an Internet-based supplier in CA (No tax! No shipping!) and hand them over to the Ace Mechanic. I use this as my long-distance driver and have put 25K on it in one year. I met an enthusiastic former 350 SD owner last year who told me to never sell it and never lend it to anyone (people put gas in the tank by mistake). I think he gave good advice.


Best Features

Classic Benz look with some updates (antilock brakes and air bags). Solid, safe, excellent handling for size. Biodiesel friendly without major adjustments. Roomy interior. Pleasure to drive


Worst Features

Updated audio system is a must for any driver in the 21st century. Currently using the center stow-away compartment for a cup holder. Doesn't handle the newer AC coolant well, so cooling performance is mediocre.

Review

My 350SD has been a daily driver for me for 9 years. This is one of the best driving sedans mercedes ever built. The car really handles a curve and is a great touring sedan on the hwy. I like the diesel, it's no dog with the the turbo and I just typically drive a little slower (no tickets). Now this is very inportant if you own this car; The turbo charger on this engine gets its lubrication from the engine oil, the turbo charger operates at such an high RPM that within a very short time "60K to 80K miles of engine operation" the seals in the turbo can go and will start blowing engine oil into the manifold. This will lead to engine loss. If you're losing eng oil replace the turbo immediately.


Best Features

Gets great fuel mileage. Big sedan with lots of room for all. Classic Mercedes look. Fun handling car even around town


Worst Features

If your losing a quart of oil every couple of days replace the turbo charger if you want to keep your engine.
