When I had DD1 I was driving my fiesta. We got a compact seat, but the front passenger seat still had to be as far forward as possible. I fit but DH didn't. If we went somewhere together he had to drive and i felt like i was sitting in the windscreen... Eventually we moved to car seat to his car (falcon), and I ended up trading his car in for an x-trail . He now has to drive my mini car
As a side note, I found it better having the seat on the passenger side as it means its on the footpath side when getting in and out the car.....
