Early buyers of the W126 in America had to make do with the relatively anaemic 3.8 liter V8 in the  380SEL. Thirsty and underpowered, it was a bit of a disappointment. Meanwhile, European customers were offered the better performing 500SEL, which was powered a 5.0 liter version of the M117 block good for about 240hp. Although MB USA eventually relented in the face of demand and brought the car over by official channels, early Euro-spec examples pop up for sale in the US every now and again, since many of them made it over to these shores via the gray market.
