Based on the given box plots, we can infer that the type of cars sold in June typically gets better gas mileage than the type of cars sold in December.

We can see that the range of gas mileage for the cars sold in June is from 21 to 33 mpg, with a median of 24 mpg. The range of gas mileage for the cars sold in December is from 14 to 26 mpg, with a median of 19 mpg. This suggests that the cars sold in June have a higher gas mileage on average than the cars sold in December.

Additionally, the interquartile range (IQR) for the cars sold in June is from 22 to 29 mpg, while the IQR for the cars sold in December is from 18 to 21 mpg. This further supports the conclusion that the cars sold in June typically get better gas mileage than the cars sold in December.

Therefore, we can infer that the type of cars sold in June typically gets better gas mileage than the type of cars sold in December.
