I owned a 72 280SEL 4.5 for two years. This car because of its age and type of fuel delivery system requires someone willing to tinker from time to time. Every part of the fuel system is adjustable which is good but because it is adjustable then it goes out of adjustment over time. The injectors join the fuel rail with rubber fuel line, the new drier fuel could cause leaks on older hoses which can be fire prone. They tended to wear out camshafts with poor maintenence. They tended to wear out valve guides which causes oil consumption. Verify front sub frame mounts are good. You can see them thru the wheel wells in front. Trans, rear end are bullit proof. Verify no trans fluid leaks from front trans bell housing. front pump seal can leak over time, requires trans r/r to replace. A/C is weak at best. Dash levers usually break that work the heater and A/C. Ck for king pin wear on front spindles. Car is rust prone behind every wheel in the inner fender. The car is rather addictive! When its right, what a blast to drive. When its out of adjustment it is frustrating. I was lucky, I was employed at a new MB dealer during ownership.

It would be great if you could remove one of the cam covers to visually look at the cam lobes. When worn, you can catch your fingernail on the surface, if good they look chrome plated because they are.

I've found that parts are relatively easy to find (except cheap manifold pressure sensors), but can run more than a domestic part, or something from a Japanese car. I love my 108 - I've got one exactly like yours. Good luck!

280se 4.5

Also the car has a computer controlled EFI system, so find a mechanic who understands these systems. Great car, if properly mantained it should feel like a modern car, ie not sloppy like other cars of its year.

Thanks

I've read all the posts and concur with everything except the cams. There was a mfg problem in the original design and the lobes wore off the right bank cam at the #1 cyl. Once replaced there was no problem. MB had the same problem with their 5 cyl diesel when it came out. I think the 108 was one of the finest chassis produced. I would go for the SEL over the SE though, but only because I prefer the longer wheel base for the room and the ride quality on the super slab.

I used to own a 68 200D which is on the same chassis, I sold that one to buy a NMW motorcycle and then sold the bike because I missed the feel of that chassis.

I found my current car, '73 280SE 4.5, at carmax (believe it or not). the fuel injection system on these cars, as is mentioned above, is an early one, and I think a carb may have been a better design choice for this engine, and a 4 speed tranny would be great on the gas milage.

but I tell you, when you floor one of these babies you'll want to fill it up.

A lot of people are fans of this chassis, the ride is great, smooth, and the acceleration is incredible for a car its weight and when it was built.

Trivia about this model. its the last the Mercs that were handbuilt and the first V8 benz engine.

watch for rust, and any leaks from difficult to get places (tranny, brake booster etc.)

I was lucky when I found this car, I was looking for a diesel model. I suggest that you look at and drive other models with the same chassis before you throw down money (which on a basket case benz can be a lot).

Good luck! awesome car!
