Coronet Super Bee Random Class change?

[SuperShouden]

So, the Coronet Super Bee from the store is a D304. But the one in my garage is apparently "stock" and a C377. Did my game glitch? What's going on?

That's one of the old exploitable musclecars; they adjusted the PI of the Coronet and several other cars in a Title Update. Maybe the update didn't switch the PI in the first spot you looked.
