[92Blue]

Hello everyone. I just found this forum and would like some advice about my car. 6 months ago, I bought a 92 CV LX with 32K miles at an estate sale. The owner parked it in the winter and was maticulous with the maintanance(great record keeping). It also sat for the last 2 years due to his illness. I've learned that it burns about 1qt of oil every 3K miles and both cats have corroded(leak). I've done all of the maintanance items that I could think of except trans fluid. Is this acceptable oil consumption? What are my options with the catalytic converters? Every suggestion counts. Thanks in advance!
