Hello! I'm Nicolay (I'm also also known as YochiEevee, EeveeEmolga or simply Yochi). Making mods for GTA San Andreas since 2014 (though I started to upload mods to this site since 2015, and the rise of my mods was started in 2017 with BMW M3 E30 being my first featured mod on this site), and I am a BIG fan of tunable cars (be it a Wheel Arch Angels tuner or a Loco Low lowrider)
If you have any questions, just PM me. Bug reports in my mods' comments are also accepted. No mod nor (default) replacement change requests are accepted of any kind since I'm tired from those, yet also (in case of default replacement change) you can just replace the cars by yourself. I also can't just take the car one right after another and make it useable for San Andreas, because I know the "quality over quanity" thing. Even PS5/Xbox Series X exclusive vehicles can't be requested because they are yet to be available on PC yet.
Current GTA SA WIP mod schedule in no order:
WIPs on hold:
GTA V Karin Boor [Tunable] (replaces Bobcat) (no interest on this one)
GTA V Dinka Kanjo SJ [Tunable] (replaces Jester) (no interest on this one)
GTA V Bravado Buffalo STX [Tunable] (replaces Buffalo) (no interest on this one)
To be honest, it looks like a Stallion with quad lights and mismatched panels rather than an actual Oldsmobile Cutlass and Oldsmobile 442. Were you trying to make something close to GTA SA Vanilla Clover?
