Note that cancelling an order can and probably will nowadays lead to a cancellation fee, as does terminating the Qashqai lease early. On top, the good condition bonus will also be reduced.
Yes that’s true if you terminate a lease early with a car that you already have (always been the case, as far as I know) but Reed wasn’t asking about that. The question was whether you could cancel an order before you have taken delivery of the car.
Edit – apologies. I thought you were referring to when you cancelled your lease. I realise now that Reed had mentioned his mothers car too, so yes you are quite correct.
