As I was considering renting a car today I noticed that Enterprise
has a section for general aviation.

"from your wings to our wheels"

Last time I rented an Enterprise car it was from a place just down
the road from N10. (They picked us up at the airport.) That
airport ID doesn't exist in their database.

Searching at IND, however, provides a list of FBOs who handle
Enterprise cars. That's handy. We often make day trips and it's
great to have a car that's ready when we land and that we can just
leave when we depart late at night.

This will save me some telephone calls. It's also refreshing to
see a big company like this recognizing the general aviation
market.
