hey ibuildit, I highly recommend the Saris 851 Bones RS trunk mount bike rack for your needs. There is simply no other rack on the market that performs like this one! The Saris 851 Bones RS is engineered to fit our 2005 Mini Copper S perfectly and you never have to remove it because this trunk rack locks to your vehicle. This bike rack is also considered to have the industry's highest stability standards. It is very easy to install it and the Bones RS stays securely strapped at all times, no need need to have to contine readjusting the straps as you would need to do on other trunk mount bike racks. The cradles prevent the bikes from swinging around and hitting each other or the rear of the vehicle. In a nutshell I describe this trunk bike rack as combining both beautiful design styling and rugged dependability. The Saris Bones RS carries up to 3 bikes.
