Hi Fondest, the car to your front seem to be a reasonable person, If you have his name the date this accident happened, I would go to the Manager of the store & state your case regards closing the car wash when that should have happened in the first instance, so too my way of thinking the car wash should not have been in opperation, your Insurance will obviously be willing to pay for the damage incured, but this may cause waves, how close were you to the 2nd car, & the 2nd car to the 3rd?
