Congats, Bill. Hope some quality time was spent with your 6-string family.
The Batmobile was sold at the Barret Jackson auto auction, just down the road from me in beautiful Scottsdale, AZ.
It will make interesting living room furniture.
I guess if the new owner can afford the $4.2 million sticker, he can also afford the AZ license & registration fees which are based on a percentage of the value of the vehicle. In this case, it will probably cost him additional 10's of thousands of dollars.
All I can think of is the number of Alembic basses that would buy...
