Let's try to keep it simple in this case. He ran some of those Marches for just one or two races. Same with the BRM - two races in the 160C, one in the 160D and the rest of the season in the 160E. So I think rating these separately would be futile, especially since we understand so little about each variant.
With your permission I would like to also replace those images with the ones I sent you so the thread is like the Senna thread
In terms of the rank - 1972 March at the bottom, absolutely. It finished almost all its races, compared to the 1973 BRM which almost didn't finish any. But Lauda often finished so many laps off the pace in 1972 he may as well have been driving in a different championship. And the BRM was running up a bit higher when it failed - in the points on three occasions.
The 1979 Brabham? Yeah, the results suggest it was pretty horrendous. Constantly breaking down. And doing so while well out of the points. Only the BRM seems to compare and I would be tempted to put it below. Actually yes, I would move it below the BRM. For a team so professional and as well-funded as Brabham, they shouldn't have made such an awful car. BRM had an excuse.
Just above the Brabham, I would put the 1983 McLaren MP4-1C/E.
