I'd look for a newer than 97 wrecked one of these.. (Copied from an article i found)
But the recent arrival of a 3,835-pound Mercedes-Benz luxury sedan, which can go 0-60 mph in 6.8 seconds, was no cause for mixed emotions because this Mercedes carries a mileage rating of 27 mpg city and 37 mpg highway.
It's the new E320 CDI diesel-powered Mercedes, and if you already have an opinion about diesel engines this car will change it. The car is quiet, there is no diesel smell, and the acceleration is better than the comparable gas-powered E320, which gets gas mileage that is 40 percent worse.
With its mileage and 21-gallon fuel tank, the 2005 E320 CDI -- available at dealers now -- should take you from Portland to San Francisco on one tank. For that extra mileage, you pay $1,000 more for the CDI than the gas-powered E320.
The new technology controlling engine fuel intake is what has really changed diesels in the last few years. In late 1997, Mercedes-Benz introduced the world's first diesel engine with CDI, which stands for "common-rail direct injection." The first truly electronic fuel injection system for diesels, the CDI system provides more precise control of injection quantity, simultaneously making more power, lower exhaust emissions and quieter operation.
The power ratings of the E320 CDI give an indication of this power: The car's turbocharged, 3.2-liter, 24-valve inline 6-cylinder is rated at 201 horsepower and 369 ft-lbs. of torque -- a torque rating typically found on a big V-8 gas engine. Unlike previous diesels, power is available quickly with this engine -- enough acceleration to push you back in your seat.
