Amazing Fuel Economy

My 1999 Cobra and I just took a trip to Nashville TN from my home in Morristown TN. Round trip it was 431 miles. Amazingly, I was nearly able to do the whole trip on 1 tank of gas. I filled up the 15 gallon tank with 93 octane fuel from Sonoco, drove exactly 400 miles before I had to stop for gas. My car has 93591 miles and only has a few minor upgrades. I bought the car in 2004 and this was the 1st long distance trip I have taken in it and the 26.7 miles per gallon blew my mind. I am absolutely thrilled with the fuel economy and can only hope that it will continue. Thank you Ford for building such a great car with lots of power and great fuel mileage.
