I agree that nearly a half million miles is remarkable for a little in-line six cylinder gasoline engine. Even though my days of doing "side work" are long over, I'll miss working on this car. Other than my own vehicles, this was the only side work I've done for several years. I promised my friend that I would work on her car for as long as she wanted to keep it and I never charged her for labor, just parts at my cost. It was the subject of many conversations over the years. Many friends and aquaintances had differing opinions on how long it would last. Whenever I drove it to work the guys would all take a peek at the mileage and just walk away shaking their heads. Now I'll see how long my '94 E320 will last. Anyone care to take a guess?
