Industry Price for 2020 Mazda 3 BP G25 Evolve

Would anyone know what the price should be negotiated down to for the 2020 Mazda 3 BP G25 Evolve? I tried the trick of calling up insurance companies and asking for total loss value within the first year but many companies cover "like for like" and will buy a brand new car to replace within the first 24 months.
Any suggestions would be great, Thanks!
