Trouble Finding A Solution/Pugin

Not sure if this is where I need to post this, but here it goes...

I'm looking for a plugin to add a tab to the users profile page (kinda like the "Recent Visitors" plugin/tab). A one-to-many entry form (with several fields I create) that the user can add, modify and delete entries from.

ie. I have a vehicle/automotive community website where I want the users (vehicle owners) to keep up with the modifications they do to their car. Each Modification would be a new entry that the user maintains.

Thanks

Basically repeating fields, we've plans to implement this capability in CB 2.0. However for now you'd need a new CB plugin to provide such a feature, but am not aware of any. There are quite a few directory Joomla extensions however and believe some are designed specifically for vehicles that may be able to provide what you need. Some example findings from JED as follows.
