Hi there, I submitted a couple of pics of the Savvyverse version of the High Roller. They should go in screenshots as they are both screenshots of the Civetta Scintilla from BeamNG.drive. This is a different in-universe version of the High Roller. I wasn't too fond of the High Roller becoming a monster truck in Kings of the Con. So, I made it into the Civetta Scintilla Dark Owl config with the off-road mode being a custom config that's separate from the main car itself. The off-road mode is somewhat inspired by the off-road mode of the Defender from the obscure TV Series, Viper. That car had an off-road mode for going on rough terrain. I had considered on it being a Lizard Cataract from Ridge Racer Type 4. But, the Scintilla Dark Owl config looked better in my opinion.
I have plans to make the Heartback as well. It's based on the Ibishu Chisai that Leni drives around in in my Loud House headcanon and it's a portmanteau of Heart and Hatchback. The Ibishu Chisai is a mod made by Nekkit by the way.
