This.
Plus SE030 Jota and VT 6.0 2001.
I'd be content with just the Diablo SV - either before or after the facelift - since we already have the Diablo GT and Diablo GT2. I think those latter two are based on the post-facelifted version, so the pre-facelift Diablo SV would be nice, if only to have a different Diablo. I also hope we get a premium version of the Diablo GT1 racecar that raced in JGTC GT500.
On that note, I still wonder where JGTC GT500 cars would fit into the current group list. We know that modern Super GT500 cars go into Gr.2, and that GT1 cars previously raced alongside JGTC GT500 cars, albeit not very well. We also know that various GT1 cars fit into Gr.3, such as the Aston Martin DBR9.
Speaking of which, I think it's very likely that Super GT300/JGTC GT300 cars would go into Gr.3, as they often race alongside FIA GT3 cars in real life, and the made-for-game Gr.3 variants of the Subaru WRX STI and Mitsubishi Lancer Evolution X have bodykits with a striking resemblance to GT300 cars.
But I digress. As for GT300 cars, I'd ideally like all premium GT300 cars to return from the prior GT games, such as the Subaru BRZ R&D Sport, the Lexus IS350, Mazda RX-7, and the ASL Garaiya. Of course, I could see some cars not making it, like the various "standard" models that were in GT300, but I could see them being replaced with more contemporary models. I am also quite sure a somewhat older Prius GT300 was getting looked at by Polyphony Digital, so that could be fun. I also don't know if it'd be necessary to bring back the 2008 Subaru Impreza WRX STI GT300, as we could potentially have both the BRZ GT300 and the Gr.3 WRX STI, though I'd personally like it if only to have an older WRX STI model in GT300.
EDIT: I also hope that if we do get any more made-for-game race cars, it allows for more automakers to compete in the Manufacturers Series, just like we can currently see in GT Sport with many of the automakers there. I could see Mini being one example of a future addition to the Manufacturers Series. This is before we consider other automakers with appropriate real-world race cars insofar they could use those models to compete in the Manufacturers Series, such as Bentley, Maserati, and KTM. For Bentley, I believe there are both GT3 and GT4 versions of the Continental. (Though if there really isn't a Continental GT4, PD might be able to create one, like they've done for many of the other Gr.4 cars we currently have.) Then for Maserati, their Gr.3 options could come in the form of the GranTurismo GT3 or the GT1 MC12 Corsa, while there is also a GranTurismo GT4 that could be used. Finally, for KTM, there's the X-Bow GT4 and the upcoming GTX.
