I've owned 2 85 Rivieras and both have been great investments. Yes, things do go wrong, but these cars offer a lot. Negligent treatment of the car by a previous owner can really affect it's reliability & performance. The leveling system goes out on all cars that had them in the 80s. It's not exclusive to Rivieras.
