Going to purchase a 2012 Prius V but the CarFax says there was an accident.

the seller seems like a good guy but I dont recognize the site this carfax is on. The carfax says there was an accident last year with moderate damage to the front but looking at the car you wouldnt believe it, there is some damage to the bottom of the bumper but thats really it, gonna check the voltage on the battery when i go to purchase it today, im paying $6700 for the vehicle, lmk what you think. thank you!
