I have a 2012 Seat Ibiza. It's been reliable for us and has just past it's MOT. We own it outright. It's not any great shakes but it's perfectly acceptable.
I am pregnant, due in October and we have a DD who is 2. Money is tight but luckily we have everything we need for baby practically already as we kept everything of DDs and know this little one is a girl too. We have a Maxi Cosi car seat for DD and an isofix base which she's always had; we still have the newborn car seat she was in until she was about 9 months before we moved her to the next size up (pebble). The problem is the isofix itself; because of the way the leg sits it pushes the passenger seat forward pretty much as far as it will go. Neither DH or I would be able to drive if the driver's seat was pushed that far forward so my suggestion to DH was we buy DD a new car seat that can go behind the driver's seat without an isofix (the Pebble can't be strapped in without the isofix) and new baby has the current set up with the isofix.
DH wants to try and sell the car and buy a bigger car so we can buy a new isofix for baby and have both children with an isofix. My car is not worth much; it's good for us but realistically it's maybe worth £1500 if that so to buy a bigger can from what we can see currently we would have to get an older car with higher mileage to accommodate this.
Is it really so bad to take DD who will be 2 years 7 months when baby is here out of an isofix. Surely millions of children use car seats without an isofix and are perfectly safe. And for the sake of keeping a car that at least we know is good enough for what we need now is surely better than getting a 'worse' car just to accommodate the child seat?
