Hi,
I thought I'd post a current picture, but I realize it is very similar to the last one. The biggest difference, you cannot see: I've removed the rear under pan, and it did not seem to hurt me at all.
My worst mileage this winter was just above 41mpg, and my best tankful was 46.3mpg! I'm looking forward to getting above 50mpg, after the weather warms up!
