Thanks TimA: I just finished my first tank of gas and had a total of 542 miles. A bit less than I had hoped for, but for a brand new car with a "supposed break-in period" I think it's not too bad. I'll do the math soon and get a true mpg figure for a baseline. Thanks for your (and everypone's advice) it's really helpful. Okay so now where can I get a large trunk net without spending an arm and a leg?...
