You can try this tweak:
1 -- Add new field 'Parking'
Go to file: /templates/ja_findus/etc/extrafields/listing.xml
For example, next to 'Phone' field, you can add this line:
<field name="parking" type="text" label="TPL_PARKING" description="TPL_PARKING_DESC" size="40" filter="RAW"/>
2 -- Render this field in article view
Go to file: /templates/ja_findus/html/com_content/article/listing-1.php
It will require some changes in several section in the file so I attached these 2 files here so you can see the difference:
3 -- In backend of article, you will see new field for Parking and add info there.
