Who mentions that they might not have much money but still enroll their son in go-kart classes?

The mention of enrollment in go-kart classes, despite financial constraints, is made by Enzo's father. This highlights the theme of parental sacrifice and the desire to provide opportunities for their children, irrespective of the challenges faced. Enzo's father embodies the commitment to nurture his child’s interests and passion, showcasing the love and support that parents often strive to give, even in tough times. This moment not only reveals the character's values and priorities but also serves as a contrast to other characters who may not have the same level of commitment.

While Denny is a central character who deeply cares for his daughter and has dreams for her, this specific statement reflects a different emphasis on financial constraints and parental investment that aligns more closely with Enzo's father's perspective. Luca and Zoë, while important to the narrative, do not express this sentiment related to financial limitations and go-karting. This difference reinforces the themes of sacrifice and support that are prevalent throughout the story.
