I feel frequency response is a near useless parameter to go by for car audio unless you see a big suckout somewhere in the driver's frequency range. By the time you get the speakers in place, you've either:
1: Focused a lot of attention on catering the application to the specific driver in hand. For that reason it will perform well.
2: Popped the speakers in a factory spot. In that scenario, all speakers good or bad are going to have a terrible response regardless.
Off axis dispersion is important, but this can be combatted with a lower crossover frequency.
