They do not seem to want to negotiate the buy back amount. Are these amounts set in stone.
Car only has 29,000 kms on it so I think the dealer wants it back to re-sell.
The lease probably deals with the manufacturer, not the dealer. Yes they want to resell it.
About the only thing your friend can do is buy it out and resell it themselves. I did exactly that on my only lease, put in for sale a few months before the lease ran out, made an agreement with a buyer, arranged for the dealer to transfer directly to the new owner, not me, to save taxes. Don't know if you can still do this, it was a few years ago.
