I have a Legnum I am considering selling. It is pretty much factory, is in great condition, has had regular servicing and has done 92 k (imported by Donnithorne Simms (Mitsi Chch) at @61 k). My reason for selling is that it is too small for 2 kids (in booster seats) and an adult in the back and it doesn't seem to be possible to get extra seats fitted in the boot (that are certified). How much can I realistically get for this privately?
