Check the composite leaf spring is not cracked, also check the rear spring and the long bolts on the ends of rear leaf spring. Check the nuts are at equal points on the thread, standard ones should have a split pin to secure them. Aftermarket ones (longer bolts) are used to lower the car, you may be able to correct the lean to one side by tightening the nut on the side that is leaning to or losen the nut on the other side.
The front spring has shims above between the crossmember and leaf spring, the ends of the front springs have rubber on them. If that has worn on one side that may be it but unlikely as they seat firmly in the lower control arm.
I say upgrade to coil overs, fully adjustable to the ride height you want no compromise.

Previous owner was extremely fat?
Related to what gerardvg said, make sure the exhaust pipes have heat shields where they run under the rear spring. Too much heat can destroy the fiberglass spring.

I've had 10 C4's they all had a lean from 1/8 to 1/2 inch to the drivers side.
