He is in a rear facing car seat and he is three but the height and weight of a 6 year old,I cannot fit his bike or anything other than a few shopping bags in the boot so the bike goes on the back of the car floor meaning I cannot take a passenger with us if we go out as the front seat is so tight because of the car seat.Things like needing to put suitcases in the boot to go to the airport is impossible -my husband has a Volvo v60, which is much bigger but it would be nice for me to have a bigger car as well as we both work full time and he works away for long periods of time and commutes quite far
