No "ifs," "ands," or "buts." That's just bad financial planning. It's a totally unnecessary luxury that holds the potential to burden the entire family.
Additionally, your definition of "middle class" is quite peculiar. The median wage in the United States is less than $30k. The median household income is less than $60k. Do you really think "middle class" families are buying cars that cost as much as one of their salaries?
