Agreed, I had ideas as to what cars could appear in Gr.1, too, even for manufacturers that already have one. For example, I think it'd be neat if the Countach QVX was another potential Gr.1 car for Lamborghini. Chevrolet could have the Corvette C7-based DPi. Even dead brands could have Gr.1 cars, like how Pontiac had a Daytona Prototype. It'd be even better if other automakers could have more Gr.3, Gr.4, and Gr.B cars, given what we know is part of the class so far. Bugatti could get an EB110 GT1 for Gr.3, and Maserati could have both the MC12 GT1 and the GranTurismo GT3, as well as the GranTurismo GT4 for Gr.4. However, I think there'd be even more options if the LMDh class becomes a thing, especially with rumors that Lexus and McLaren would be interested in that class. I think as it stands, the current class system has a lot of potential for further development, and especially if they have events that limit what cars can be entered, like a Gr.1 event just for Group C racers. But ideally, as many automakers as possible would have a car in Gr.1, Gr.2, Gr.3, Gr.4, and even Gr.B. Maybe even more classes could be made, like a Gr.C for older, pre-Group B rally cars like the Lancia Stratos or the Alpine A110.
