I would say no to serrations, yucky. I would however like to see a stub for a window breaker and a place for a web-cutter even if I have to do that one myself. If the price it right I would not mind doing some self-mods. With my 6month old strapped in a strapped in seat etc. I am getting anxious about when, not if really, I live in Houston, we get into a not so easy to walk away from crash. Probably stupid but that is the way my mind is working right now.
