Starter life depends on a lot of factors. You have time of use, weather conditions, engine condition, and electrical system condition. Salty, humid climates can cause the starter components to prematurely get worn out and corrode. A neglected, sludge filled engine will put more stress on the starter to turn the assembly over. A poor battery and electrical system (corroded wires, etc) will cause unwanted strain on the starter motor. And of course, the amount of time in use is what puts wear on the internal brushes.
I wish there was a clear cut answer for you, but it's more of a, "It was fine right before it stopped working" situation. Luckily, most of the time you can hear it slow its' pace and it gives you an idea it may be soon.

Yeah im aware of the factors, and coming from hondas where the starter life is around 50-75k for the older models, im amazed at how well our cars our built. I was just seeing if anyone on this page has had to replace theirs, and at what mileage. So far, everyone is original, so thats fantastic!

My 2001 e320 4Matic wagon has 198k with original starter.
The failure occurred after the car sat for about 5 weeks - no other symptoms or problems to indicate the oncoming failure. I replaced it with the starter from my parts car. Interestingly, the starter / solenoid connection on that one was much thicker wire.

Some left family with about 300k miles.
The only problem was SL500 with 196k where starter gear would occasionally free-spool.
I found nice starter on JY for cheap, so replaced whole thing to not worry about dissasmbling the gear.
Starters replaced = 0.
Currently, I have a 99 E300 Turbodiesel.. 242,000 miles. Original starter and alternator are still kicking.
My highest milage MB to date was an 84 E300 with 536K. AFAIK, I let it go with the original starter.
I don't think you have anything to worry about...
EDIT: I thought I should add that on my E300 I have had experiences (i.e., injection pump failures, -23F cold starts, etc) where I have had to do some serious cranking.. to the point where I was kinda expecting to destroy the starter and nothing to date has phased it. Hope that helps!
