If you knew the accident was in 2015 during the rental period.I did look at it - and the accident was in 2015. So if something was going to die due to the accident it would have done so already!
Then there is no basis for your post.
Estate Sale tells me that grandma or grandpa had a low speed collision.
Worth a look IMO.
Because the collision was during its rental ownership period. not the lower mileage later owner.
