Snap! We have the carbriofix maxi cosy seat and we have a three door polo. It's no more hassel than in a five door in my opinion.
The bases aren't essential, just make it a little easier to get in and out, but honestly after 2-3 times with the seat belt, I was a dab hand at it. You can also use the base on mine to have the seat forward facing, but I've heard mixed things about the safety of being forward facing.
