So many of these newer 'refreshes' or 'reimaginings' of classic cars are missing a major piece of what makes the old ones great: actually winning at racing.
At least to me, the 3.0CSL is special because it is a winning homologation car, like the Delta Integrale, the Evo, the STI, the Escort Cossie, the AAR 'Cuda, the E30 M3, etc. These cars are special because they (or their nominally-similar brethren) went out and won races. That successful competition made the cars even more special at the time, and that hasn't diminished. Even when compared to other homologation vehicles that didn't win, the winning cars command a premium, since at least some buyers considered it when purchasing, and car nuts like the winning cars.
If BMW wanted to actually make a worthy successor, they would make a winning racing car in a series that required homologation. That would be something really special, instead of some carbon bits with racing stickers. That's part of why I'm interested more in the GR Corolla instead of the Civic Type R, for example, since the GR Yaris was actually supposed to rally.
That said, I get why they don't. It's much cheaper to make what they did and cash in on the past instead of actually adding to the heritage.
