I was wandering around Enthusia's menus and found the car license page. One part said: I haven't seen any racing Suzukis, are there any? Or is it just what Suzuki told to write?
The only Suzuki in the game is the Cappuccino, unless there's some non-playable Suzuki in the background scenery. It could be Suzuki's standard text for a license, or it could be interpreting a Lv10 Cappuccino with modifications as a "racing model".
I noticed that too a while back. I was crossing my fingers for a secret #212 car unlocking if you did everything in the game. Unfortunately, that's not the case. I think Wolfe is most likely on point with his speculation though.
