Hi! I saw your Honda Civic 2020 ad. You're selling for R$85,000, right?
That's right! Very well maintained car, single owner.
Looks great! But I need to know: has it ever been in an accident or had any issues? It's very important to me.
Não, nunca teve nenhum problema. Carro em perfeito estado, só uso para trabalho.
Perfect! I'll make the transfer and pick it up tomorrow. Thanks!
