While the cars may seem redundant, they are perferable to the stock cars. They provide 10 more passengers per car and a 5% increase in profit per car. That's why they are called "Extra" as they provide those extra increases.

Best bet is to earn them and sell two of the stock cars from your train set and replace them with the award cars.
