I do think you can get a pretty good deal right now. Make sure they recognize that you don't need a car today, but if they can sweeten the pot enough you would buy.
As far as should you, that depends on your own level of security (job/income).
Now is really a time to try to stretch your money as far as you can and try to save for those worst case scenarios, until the path out of CV pandemic becomes clear.
As an example, I just had three concrete terrace walls in my front yard covered with a stacked stone facade - something I had been planning for years and I had it quoted before CV had much traction (mid February), The work ended up getting done in early April.
Looking at this from an economic standpoint, by April it was clear that there is a good chance I could get the work done for substantially less if I waited another month or two when there would be more people looking for work. In my case I am retired on a fixed income and while my 401k's have suffered quite a bit, I also figure these guys need the work, I just hope that they are stretching the dollars I gave them as much as they can.
That is my 2 cents.
