Read about the spring perch failure. There's lots of info, but it shouldn't keep you from purchasing the car.

I just bought a W210 ('98 E300 Turbodiesel) about a month ago. I've driven it nearly 3000 miles, for a total of 175k on the odometer. It's a fun car, cheap to operate on B100 biodiesel, four airbags, etc. Not even too slow...for a diesel!

Cheers, John
