I bought the S3 SB as a baby car and I've found that it's a good car with plenty of room in the back seats for one of my mrs or I to sit in the back alongside our baby in the baby car seat. But I'm finding that the boot is too small!! We can fit everything we need for a trip out in the boot, but it is a tight squeeze! And we certainly can't fit much shopping in the boot once the pushchair, pushchair seat and baby bag is in the boot. We've got a quinny buzz pushchair which is quite heavy and bulky - but it does feel really solid and absorbs the bumpy pavements around here really well. It's also good that the maxi cosi carseat fits on the quinny frame so for short trips we can just keep the baby in the car seat and move her between the car and the pushchair (frame) without needing to disturb her. Does anybody have any recommendations for an alternative more compact but still solidly built push chair? Our baby is 1 month old. At the moment I'm contemplating selling the S3 and getting an A4 avant or an A6. We've only had the S3 for a few months! Does anyone else use their A3/S3 as a baby car?
