it looks as though the drivers side rear wheel has some camber on it, hard to see from this pic i know:
then the passenger side looks fine:

but its the passenger side thats rubbing.
could it be the geometery as the prev owner did the shocks and springs himself.
i have had a good look over the car and i cant see any welding or accident damage?
im really confused about this and i need it fixing as im doing a long trip in it soon and the car is going to be full of people.
could coilovers be the answer?
