I’m tempted to enter my Oldsmobile in a local autocross, but I have no idea what class it would fall into. It’s a completely stock ‘65 Oldsmobile 98 with the 360hp 425, and a curb weight of 4250... The only potential issue I see (other than having only lap belts) is that the wheelbase is 126”...

Any autocross gurus want to venture a guess about what class I’d fall into?
