Nice work on these modifications which are actually similar. I do have a couple of questions:
1) I don't see any search fields. Can the data you collect in this database be searched? If so, how? Is there any ability to search by field, e.g. by car manufacturer and by year made?
2) Are there dropdown entry fields? All I saw was text-based input. So if I wanted to limit the entries to 10 items in a dropdown, I didn't see how this could be done.
3) Is there a demo site? Very difficult to get a feel for this with pictures.
4) What kind of code hacking is required, if any? I'd prefer to leave my core files alone as much as possible.
