Take a Buccaneer, drop it on wire wheels, and let the paint do the talking. The Buccaneer Custom is the lowrider treatment of Albany's 60s coupe, first built through Benny's in GTA Online and now confirmed for GTA 6 through Trailer 1 and screenshots. Expect the same relaxed muscle underneath, with considerably more attention from everyone you pass.
Rockstar has not confirmed how the Custom is obtained. In GTA Online it was a conversion of the standard Buccaneer through a specialist shop, and a similar upgrade path in GTA 6 would be the natural guess. Nothing official yet.
It was confirmed through Trailer 1 and official screenshots.
