In her early 20's and before I knew her, my better half was in a terrible car accident. She was completely gone. But they kept working on her and brought her back from death in the air on the chopper while on her way to Westchester Medical Center. She spent some time in a comma, then in rehabilitation, and then came the reconstructive surgeries.
I guarantee you, that if anyone has a free pass into heaven it's definitely her. Yet, she didn't see any bright light either. I'm convinced both you and her didn't see anything only because you both were simply too early for your invitation.
My Buick is the same except for a few more scratches, road rock chips, rust bubble and some slightly tarnished aluminum. I drive it whenever I can.
