Thanks Dan, that is most useful especially the advice of leaving a cable there hanging out.
The one I have bought (pick it up on Friday) is black with black seats ... was wondering about the lighter grey interior but was not sure how it would cope with being marked.
Thanks Rayaan, if there is a cigar type socket in there then it might be better for me to use that instead then and leave that cable there instead.
That range puts my mind to rest with it then.. thanks for the info.
