but the performance is just not there, in factory street spec. Worst is that the body is so beautiful, it promises more than it delivers. And the interior is rather "thin" (common for Bimmers of that era, but the M6, a bit later, was "plain" yet very high quality - leather, padding, stitching.) This was all before Bimmer luxo-bloat, of course.
Bottom line - a great car, and as progenitor of the M family, to be respected, but incongruous and didn't manage expectations well.
Now one of the Procar specimen, another story entirely...
