Welcome to the forum mrandmrsh - you cannot escape from some of us ;)When I got my G4 I was told the winch rope would be replaced with a new one as Land Rover cannot sell used ropes for some legal reason. You will probably find its not an orange one but as already mentioned make sure its not a wire rope they try and supply you with. Also the roof lights will come disconnected - ask to talk to the techy who disconnected it on how to reconnect it should you hve to use them off road. FYI, mine were just unplugged under the expo and was a 20 second reconnect job.
Somethings I wish I had checked prior to buying mine.
Tyres - Make sure there are no nicks in them. I forgot and whilst the tyres have loads of tread they also have a coupe of small nicks in the inside side wall.
Sills - See if you can take the sill covers off. I found one of my sills is dented and now cannot get the dealer to sort it. They may of course charge you for new clips but these are peanuts.
Underneath. Check for any obvious damage to the covers (gearbox) etc. Again I failed to do this and subsequently found them well damaged
Remember the cars spent more time off road than on so just make sure you concider this.
Saying all that, I wouldn't change mine or have stopped buying it had I found the above damage.
Any more questions, you know how to contact me.
