Good Engine and Body parts

I do not know if the engine will start as I have never tried to start it. When I bought the car the owner told me it had been a daily driver until the man that owned it passed away and the car stayed out in the elements for several years. I was afraid to try and start it before changing all the fluids. The motor is not seized, t will spin. I tried to show in the picture the rust on the passenger floor board and along the rail. I'll stop by the shop and try to jump it off and see what happens. Also the right rear wheel axel has been taken loose (not sure what the problem is there). Car sold as is where is so bid accordingly.
