I have the 2010 Mazda Neo BL series - Love my car, brought it new and all by myself
The hatch is quite roomy, but if you have children that are still using prams, I'd advise to take the pram down and see if it will fit!
The only difference I found - back when I got mine - between the cars with the same engine, were the accessories.
Also I have the 6 sp manual, the only critism I have is that you feel like you have to move through the gears alot quicker. But other than that, no other complaints.
