We were looking at new V70s in a showroom yesterday, and liked the integral booster seats which come with the "Family Pack" (UK spec). These are a pair of booster cushions which pop-up from the rear side seats. But realistically we'll be buying a used car, and so wondered what the options are (or rather, were). I seem to remember that the V70 used to come with an integral booster cushion or child seat in the _centre_ of the rear seat. Is this the case? (I've noticed in some used car adds mention of "integral booster" (singular) which would appear to back this up.) What's the chances of fitting any of these aftermarket? (...like you can fit the rear facing 'third row' extra seat). Also, they're neat, but are they worth it? Does anyone have them and regret buying them? Or think that the same thing could be acheived more cheaply by buying a 3rd party booster? The main advantage that I see over a 3rd party booster is that they're narrow and neat, whereas eg. our current Britax booster has 'horns' on the side, which make doing up the seatbelt buckle on it or the adjacent child seat (3 children) very awkward. I'd appreciate any experiened advice, Dz
