Welcome to the Independent Online Mainstream Cooper Register website.
The long-term aim of the Mainstream Cooper Register is to gather a comprehensive record of as many surviving examples of the car as possible. We believe that by presenting this record in the format of a forum, we will have a register that is fully accessible to it's
members and the general public. We also hope to
provide a central source of information, images
and data on the car.

The Register is completely
free to join and is run
on the pure passion
of the administration
team. You can find
the main forum by
following the link at
the side of the page
but before you go,
take a few minutes to
look around the site.
Here you will find
detailed technical data
and information on the specification of the Mainstream Cooper.
