I did a little lookin on
www.e31.net about the 8ers, I love em, I want one, and I will buy one soon =) . Anyways there was an 830ci, about 500 of them or so was first made to try for gas economy, wrong choice by BMW since the 4300lb car needs at least a large displacement V8 to be considered a sport touring car. In turn they used those models as the crash test cars, each prototype was valued at almost a million dollars US market at the time, ouch! I was also interested in the M8 myth, but they only made way less than 20 of them, and there is only ONE left "sitting behind boxes in the BMW storyard", which BMW plans on destroying in the near future ='( It is an amazing 500hp super coupe, which they just gave the CSI package the title of the Motorsport division since they are specially tuned all around, marking one of the finest 8ers produced.
