I dunno, I'm a big fan of the Yaiba bike because it makes me feel like I'm Kaneda when I'm cruising Night City. I also drive the Quadra Type-66 "Cthulhu" quite a bit.
Jackie's Arch is what I use 90% of the time. I like the Rayfield for the in-town car race, and the only vehicle I will actually buy is the Javelina because it handles romps across the badlands better than anything else.
