My '84 380SL gets around 22-23 mpg on the road, at 70 mph, w/cruise control engaged. As I recall, back in '68, when I graduated from college and bought my first car, a '68 GTO, which got worse mileage than the 380, and I was paying around $.40 a gallon. Crunching the numbers: An Army second lieutenant made $325 a month, plus $110 jump pay, plus $47.88 subsistence, and a little later, $65 hostile fire pay. Now, 40 years later, I make more than 10 times that, and gas has only gone up 10 times , so I'm ahead, right? So, what the heck, enjoy it. Cheers, Ned.
