Following being involved in a collision deemed as my fault my insurance is about to rocket. I am still within my first year of driving and am so worried about what to get.

I drive a lot and really require something with enough leg room in the rear for my sons as well as something that has good n-cap results).

I'm looking for second hand and up to about 6k to spend.

Someone mentioned Mazda do a couple of good models....any thoughts?
