I recently re-acquired my 99 E300 that's been in my family for about 12 years now. It has lots of sentimental value. My father bought the car when it was 4 years old with 122k miles. It was sold to my neighbor a few years ago, about five and I reacquired it from him for an excellent price. It's a fully optioned model. It has everything from the Xenon lignting package with headlight washers, very rare #199 Obsidian Black metallic with black leather interior, heated seats and the very first Mercedes Benz navigation system. Only ootions it's missing is the rear window shade and parktronic.
Hands down this is probably my favorite Mercedes I've owned. I got 32.5 mpg recently going up past Wilkes-Barre and back down the turnpike to Philly onthe same tank I left with. Great torque and highway power, and still rides excellent on its almost 20-years-old shocks and springs at 173k miles (very low mileage as well). I've put about 3k miles on it in less than a month.
Here's some pictures of the beast as well. In my opinion, this is the last Mercedes that was well-designed besides the w211. I'll probably buy another one this winter I'm thinking.
