Im sorry, you are absolutely right.
I have been doing this too long and chased down too many published offers only for them to be not as advertised or disappear in front of my eyes. I am so cynical, if the offers do not say £x off any order on x vehicle. I tend to assume it’s a single stock vehicle that the dealership are having to pay for as they have had it for a while so want to offload quickly. I do hope this proves to be the genuine cracking offer we all hope it is.
