Fit well in the MINI (tin top)

I would not recommend that seat to anyone, even if it did fit in there, and I don't think it does.

Just get a Maxi Cosi or a Britax seat, these are designed to be the safest in their class, not just designed to pass the standard, and the child is in a more reclined angle in those seats which is better for the developing spine.

If you want to know more about that which seat is the best, I recommend you track down the report done a while back. New child car seat laws (http://www.which.co.uk/reports_and_campaigns/cars/reports/safety_and_security/Car_seat_changes_news_article_557_95181.jsp)

Already got it unfortunately!
He will only be in it another couple of months at most, then will be getting next stage, will do a Search for when I get that seat :)

So how can you already have it and then ask if they fit in the car?

Currently have an Audi, but thinking of changing very soon as at moment i'm on a MINI sabatical, so just wanted to know if it would fit in nicely or maybe look for an alternative seat for now.

Well got the car, and it fits ok with the base, now to find a buggy that fits in the boot :p
