[Quebec] “I am not the seller please email…”

I’m trying to buy a car on Facebook market place and it is now the second time I find a listing from an account that looks legit and they they say something along the lines of; “I’m not the seller please email this person”. Then on the email the person gives an elaborate reason to why they’re selling the car and they say that they’re letting some other company handle the sale. Then they ask for my phone number full name and address. I’m not comfortable sharing this info and I feel like there’s something fishy about it, but I don’t get what they could get with this info. I have attached pictures of the emails sent by them. Has anyone encountered this? What’s the scam?
