I got my GTO Sept 25. Needless to say, it's just amazing. I was very impressed to find out the kind of gas mileage I was to expect on the highway. I came from a VW Passat that got 30, so an EPA rating of 29 for the Goat (with manual) seemed great. I'm so far from it though. Right now it has 1100 miles, so it still needs a lot of breaking in I'm sure. But right now on the highway I'll get around 24 doing very easy speeds. I average 16 when city driving is involved. And if it's all city, I'm around 12, driving very reasonably. Not good. I hope it improves as the miles pile on, as they are doing very quickly. Any other feed back on your experiences with mileage would be greatly appreciated. Thanks, Brian
