Last mention of L.J. in the series.
When Rita shows up at Rockford's trailer she is driving an 1971 or 1972 Cadillac Eldorado convertible, easily identified by the faux vents behind the doors which were eliminated for 1973. Rockford remarks that it's a $10,000 car. The MSRP for the 1971/1972 Eldorado convertible was approximate $7,500. By 1979, this would have been a used car worth much less.
