Thaanks for the input mate, i spoke to the friendly staff at Coughrans here in Toowoomba and apparently i can adapt a commodore third row to fit a range rover just have to have the engineer approve it, i might see where that goes as i know where a seat is for sale right now.
I don't think i need to worry too much about that right now all my kids are under 9 years of age, so hopefully i'll get a few years out of it.
thanks
