So what's in the car?

Half the country sang along and nobody answered: what's in the car? At last someone opened the doors, and among bags and boxes there are eight people swearing they didn't hide the microphone.

Suspects

• Álvaro, the car's owner: He opened the doors live on air to show what was inside: shopping bags and a packet of napkins.
• Brígida, the neighbour across the street: She saw everything from her balcony and can't understand why nobody asks her anything.
• Celso, the influencer: He made a remix of the chorus in ten minutes. It already has more views than the whole concert.
• Dora, the amateur fado singer: She sings fado at family dinners. She swears that chorus was hers and somebody stole it first.
• Elisa, the radio presenter: She spent the morning asking listeners what's in the car. She got four thousand answers and none of them right.
• Fernão, the local mechanic: He's opened that car twice to fix the radio. He won't say what he saw.
• Gilda, the kiosk lady: She sells newspapers opposite the car park. She reads them all before selling them.
• Hipólito, the parking attendant: He parks every car on the street. That one he never managed to.
