I agree with completing/running Targa Florio and BRM1/24.
If we are going to run Ford V Ferrari I think we should open it up to Scalextric Ferrari P4/412 cars with 3D printed chassis. There are number of Ferrari liveries available. Of course, they might find it tough against the Slot/it GT40s. How does the Policar Ferrari run?
I would also go for Thunderslot
