I'm grabbing one of the "normal" CG locks for the baby seat.
Will be able to be used for that, a booster seat and then for an adult seat once the baby is bigger
With the one I already have there will be 3 in total - 1 for me, 1 for passenger and 1 for car seat.
If you switch cars with the baby seat the other may be heaps better though (the CG locks aren't something that you'd swap between cars regularly)
Did you already get and install yours Gary?
Impressions?
