With ~1000 miles so far in just four days, getting ~7 liters/100 km! Top speed so far has been 128mph. Haven't really been pushing it too hard. Averaging around 90mph. Traffic and construction have offered few opportunities to open it up for long. Sorry about the mixed units but I'm using a portable GPS to navigate and I'm too lazy to set it to metric. This is a great little car. Much improved over the diesels of old. I wish it was available in the US. I was surprised to see that the badging was removed on all of the AVIS Mercedes Benz vehicles in the Frankfurt lot.
