Congrats! Sounds like a heck of a ride! I bought a lighter cover at Auto-Zone or Advanced Auto from their 'Help' line of products. Fits perfect and has the 'no smoking' emblem on it. Looks great!
I did that because the first ride home in our XF, my wife said "whats this button do?" and pushed the lighter in. 10 seconds later the thing popped with the force of a ICBM. It landed on the seat behind my wife. There were a few panicky seconds trying to find that thing!
