Would be amazing. The whole reason i bought my M3 was because it was a great daily, but also because i missed having a manual too much. I wonder how much this swap costs but im sure it might be close to a used f80 price.
Only downside would the performance drop. No 200mph. And possibly more drone on the highway if the rpms are higher. 7th gear at 80mph im like at 3300 rpm.
