If you want the deal to be 100% written in stone at the time of ordering you need to make it a condition of signing and get it written on the order. Done this a couple of times in the past and even then on one occasion the garage tried to wriggle out of it by saying the salesman did not have the authority to do that type of deal, they lost that one.

Funnily this has just happened to us, put a deposit on a car just before lockdown everything agreed in writing, we have the paperwork, px is over what it should be ( I think anyway) , garage phoned a couple of weeks ago to arrange safe collection, chap said that they will honour the deal, they phoned today saying the salesman had made a mistake ( despite it being checked and signed off by two other people, one of which was the sales manager!) it turns out they didn’t include the finance payment still owing, and they are paying it off..they sai£ they will take the hit, but I’m picking it up on Saturday so there’s still time for them to come up with some way out of it,

This is very annoying and I suspect they do want to undo the deal but we don’t know for sure or at what cost to you. Why not hear them out so you know what you are dealing with.

If it’s then not acceptable to you then , as others have said, get your deposit back and walk.

If this is their attitude to a signed deal, what would they be like if you had a problem you expected them to fix under warranty?

Get the deposit back and run away.

Most recent post was on Sunday. I'm sure he's still around.

Dealership called to say the deal stands ??

They did or they didn't??
