I posted this on Products as well, but I've just realised that there is a specific cars section too!
We currently have a Vectra which just about fits two backless boosters and a baby car seat. DD2 will be starting to use her sister's old booster seat in a couple of months - one of the ones with a back and sides - and no matter how much I push, I just can't get all three seats in the back. I'm not worried about what my car looks like, but it needs a nice wide back seat, a big boot and preferably not be prohibitively expensive when it comes to petrol, tax and insurance. We'll be buying second hand, so cars that are out of production are an option.
Someone recommended the Citreon Xsara Picasso before - has anyone had one of these?
I'd be really grateful for any suggestions you may have!
