To change the value of available, you do:

davcarlist[i].available = false;

To remove an item from the array, yo do:

davcarlist.splice(i,1);

Where i is the index of that item in the array. For instance, when i is 0, we're referring to the Fiat.

By the way, "JSON" is a string, a serialized version of a Javascript object. What you have there is an array.
