We can get a pram and a full shop in our standard seat leon with 1 child, he is 2 so still use a baby seat.
So I can't see how the current car you have isn't big enough :s
I sense you just want a new toy
Since when is an A4 estate too small for a 1 child family
^^^ This.
My sister has 2 young kids, and the "big" family car is an A4 Saloon.
I found the A4 Avant had quite a small boot for a 2 small child family. Cabin space was fine unless you wanted to chuck in 2 kids and a grown person in the back.
Problem is the size of prams nowadays, they are sodding huge!
And car seats, at least whilst they are rear facing.
Obviously it's possible to get by just fine with the likes of an A4 (we fit toddler and dog in the focus estate and would manage another proper baby seat if need be) but it's not difficult to see why the op might fancy a bigger car
I've always been used to having bigger cars (Toyota Avensis, Volvo S60, Honda Accord Tourer, Audi A6, Audi A4). I've therefore become accustomed to having plenty of space and not having to cram everything in.
With now having a child the A4 is "tight". The pram will only just fit in the boot with the parcel shelf down and it means forcing the top half and base in next to each other and the wheels scuffing/dirtying the top. I then have to put the other bits in the boot inside the pram and take them out / put them back in every time I get the pram out. The baby seat in the back seat means moving the passenger seat forwards quite a bit and the access on the rear doors is low and quite narrow to get a car seat in and out. It's also a real squeeze to get 2 passengers in the back with the seat even on short journeys.
Ultimately the A4 avant isn't that big for an estate. A friend has an Octavia hatchback and wanted to look at mine. We both agreed he has as much space in the Octavia.
I absolutely don't need to change my car but I will use any excuse to change to a new toy . The excuse this time round is in the first 4 weeks alone I've got fed up of having to cram things in the boot.
