After buying and installing, and then driving on it just three days ... I recommend this starter. I paid $225, which included s/h. Had to wait 10 days for it. Compact, and mounts lower (near the oil pan). Did not have to mess with the heat shield (I have Disco one, and don't remember what the RR one looked like except that it was smaller). The wiring is configured differently, but I didn't need to buy anything else -- just had to bend the heavy cable connectors. Overall, it was slightly more hassle to install. The engine spins much faster than OEM. I consider this an upgrade.
