Just found out I'm about to be a dad for the first time (at 41 as well!). Looking at the Britax web site for car seats threw up a problem I had not considered. My Signum has front passenger and side airbags. Whereas most cars allow you to disable these, usually via a key or switch, Vauxhall decided to go one better and it looks like the only way to put a rear facing child seat in the front seat is to buy the "transponder" seat from Vauxhall at £300 + £50 for the 0-9 month insert. I have looked at other child seat manufacturers and no-one seems to indicate that they can provide seats with transponders. 2 questions: 1. Does this mean I'll have to but a Vauxhall seat at £350? 2. If so...anyone got one they are no longer using and are willing to sell?
