600 miles in 3 days...

In the 1980SD Hopping from town to town working. I was a little worried about having to traverse the metro Atlanta area three times but the car did fine

I travel as part of my job and decided the SD would be a good car for travel. I've been traveling about three years (the last two years in a late model Cadillac) and just felt like doing something different.

I was afraid that this MB "experiment" would end with it being a project car and me back in a late model car but I think it's going to work out

Is it going to work out?

I drive service in mine... around 300 miles a day. (I put around 600 miles on my TD today, and another 150 ish on my truck...) it's developed LOTS of stress cracks... inspect the front subframe and the mid line around the driveshaft cover...

oh, if it's cracking, visual inspection is all you'll need... it's pretty obvious.

so at what mileage do stress cracks typically begin to form?

When I got my first Mercedes, a 1979 300sd, I posed the same question on the old email list I was on at the time. Sort of buyer's chilly feet I guess.

I was astounded at the responses I got, not only from the South and the West, where the climate would be favorable to begin with, but from people in the midwest and up and down the east coast who were braving the winter elements and doing major driving while doing it.

I was mightily impressed and continue to be. Which is a good thing, as every other person I know thinks I'm off my nut for bothering with these old cars.

Drive it and have fun.

I have to agree with Zacharias. Just drive it if all is well.

I don't have the SD. But, I sure wish I would have bought one now. For the better part of 11 months last year I was driving 720 to 1040 miles per week (over 5 days) with my 300D. I virtually had no problems at all except a speedometer cable failure, a voltage regulator failure and an oil leak at the turbo oil drain. All of the above was inexpensive and relatively easy to fix. I don't drive the car much anymore as I have a newer one now. But, it is ready to do it again if the new fails me.

I am enjoying the car! I made the mistake of running the idea of selling the Caddy for a cheaper more fuel efficient car by my wife

Well, she made sure I expedited that *****! I wanted to keep the Caddy AND have a vintage MB Probably for the best because the MB is getting a lot of attention that it otherwise wouldn't get if I still had a decent backup other than the wifes car.

I'm trying to spend the money I'm saving by not having a car payment on the SD and it's coming along pretty well. Lotta nickle and diming though...

I think that the fact that most W116 300SD posts are about AC problems is testament to decent running gear At least most of them seem to be rolling well enough that drivers are concerned about comfort

I could not have done better on my ownership experience with my '79 300sd.

A few weeks after I purchased it, with almost no history, I went on a 3500-mile, three-week road trip. The only mishap was a blown wastegate hose somewhere in New Brunswick.

I drove that car for six more years day, night, winter and summer, including about two years where I did a 700-mile round trip almost every weekend. I often drove back in the wee hours of Monday morning on a secondary highway and never gave breakdowns a second thought... until the chain snapped half a block from home.

I put a used motor into it and drove it for two more years, until 2005. I sold it to a farmer who drove it until 2010, at which time he had let the body go right to hell. Unbelievable, never seen any Mercedes with that many gaping rust holes all over the body. Real #sshat, that one. Too cheap to oil spray it every year (huh?).

tech, This is the first I have heard this- w123?-seems like the subject would have come up more than a few times here with the folks trying to never buy another car. where do the cracks form---inner a arm thru bolt/crossmember area? theres lots of info about the newer w124 top spring mounts cracking away.

Curios about this myself as I've never heard of any kind of stress cracks on anything besides the W210 spring perch failures which are not really stress cracks as such.
