I was wondering where Who has The Batmobile

Good question. Surprised its not in a museum somewhere.

The original Batmobile is still owned by George Barris, the car customizer who built it for the series.
Three repilcas were built in 1966 using the original as a mold. During the series run and for years later, they were used for publicity tours and exhibitions. One of the replicas was really suped up and used for drag racing. Those threee are now owned by private collectors.

this website has lots of info and pics of the TV Batmobile:

According to Wikipedia, the original Batmobile is on display at George Barris' Museum/Shop in North Hollywood, California.
