I just recently returned from a 2000 mile road trip in my '96 C220 (one of many trips similar to it in the past) and it performed flawlessly with impressive gas mileage (average 34 mpg). This car now has over 112,000 miles on the clock, and like the Energizer Bunny, just seems to keep going and going. I am just curious to know what the longevity of these 4 cyl engines is, and what are the higher end mileages are out there on the C220's.???
