4x4 type car that fits 4 car seats - please help!

[Safifi]

I have done so much research it's maddening.
I have a 7 year old in high backed booster, 3 year old in forward facing, 1 year old in rear facing and one one the way. Therefore I am in need of a roomy vehicle with enough boot space for double buggy. We currently have a Volvo XC90 but there is not safe room for three carseats in middle row and not much leg room in back row. We can't have a normal people carrier as our farm lane would ground them out as they are too low to the ground. I have found many cars in other countries that could be suitable but I can find nothing in Britain.
Any ideas gratefully appreciated!

Disco.... also the 4, which is the one before last, is actually slightly larger than the latest incarnation....

Realistically how much longer will the 7 year old need a car seat and would that make a difference to car choice?

I don’t know if they are available in the UK but afford Expedition would easily fit 2 adults 4 car seats and have room to spare.

Ah, it was only the cybex solution m3 that fitted 5 in the Q7. You literally have to look at the compatability of every car seat with every car and every seat place in the car. Theres very few booster seats even that are considered safe in the back two seats of 7 seaters Such hard work. 😅😥
