Hi Mattlamy!!
Bet you are excited at the prospect of becoming a dad- congrats!
NEVER have a two door car with a baby, being a spoilt princess i refused to let go of my beloved ford KA with my Becs n/plate and bought the smallest buggy/pram i could get just to prove a point!!!(lol)
I struggled for 2 weeks (yes thats all) before i gave in and stole my husbands 5 door escort, he had to drive about in the girly becsmobile (inc fluffy mirror bits)until i agreed to sell it to buy a larger diesel car(8 monthslater).
Poor thing, but we now have a Ford Mondeo diesel and it seems for 1 baby the perfect size, manly too!!- large boots are essential.
when i venture out with friends it can be a squeeze but it was a good excuse to buy a quinny zapp pushchair...(folds up tiny- not ideal for little babes as it doesn't recline) but apparently the maxicosi car seat fixes on to the frame?!
However not one to influence, if you have a decent budget it is prob worth getting a 7 seater- or an estate.i know we will when we have another baby,we had just bought a bigger house so we didn't have enough for one this time round.
The VW tourans are pretty roomy and nice to drive, my parents have one, we managed 5 adults a babyseat, buggy (the pram) and luggage for a weekend away and weren't squished!!
As far as carseats go, i had a mamas and papas primo viaggio carseat with a base that stayed in the car, the seat clicked onto the base and the belt stretched around the seat to sturdy it,very easy.
I have a friend with a newborn and she has the isofix system and it is pretty good, incredibly simple!!
Anyway enough ramblings- bet u wish you hadn't asked!!
