Lately, it seems as though your old 300D may have almost as much value as an E320. The prices I see on ebay, wow!

The wiring harness problem is generally thought to affect 92-95 model years. I have heard of a few '96's being affected as well. '93 to '95 I believe are ALL affected guaranteed.

On the highway, you can expect around 25 mpg.

The '97 and '98 6-cyl E's use a v-6. Your 4th question is almost religious in nature
I have both and think they are both good. The E320 M104 (twin cam straight six) does make more horsepower than the M103 and has about the same fuel consumption.

Good Luck,

I agree with your answers except for one thing.

The 1997 E320 W210 class has an I-6 engine.

Not in this weather!

I'm very fond of my 123, but it is rusting out. I live in Maine, about 200 yards from the ocean, where they wildly salt the roads all winter. And to add injury, the car rides back and forth to islands on the ferry service, which are veritable salt baths.
A couple years ago I bought an '84 300TD wagon with a shot engine. The idea is to transplant the 5cyl NA engine and 5-speed manual out of the rusted sedan into the wagon. Seems like a car that my teen-age kids won't be likely to get into TOO much trouble in, and good for family trips.
The other day I wind down to the "local" Mercedes dealer (only two hours away) and drove a '98 C240. Nice enough car, but too small inside, and they aren't reported to get that much better mileage.
