The very last RWD cars engineered by the old Chrysler Corporation were produced on December 23, 1988. These were 1989 models. Most of the changes for the '89 model year were incorporated into the late '88s, beginning that May. Beginning with a supposedly beefier k-frame, also added were the driver's side airbag (with a new dash, and relocated cigar lighter), along with standard delay wipers and tilt wheel. Actual changes in '89 were a new lock-up solenoid for the torque converter, and upgraded sound systems. All other features, options, and colors remained the same (beginning late in the '87 model year, when production began at Kenosha). Chrysler Chairman Lido Anthony Iaccoca had been after the M-body for some time, of course, but the profitability of the 5th Avenue and continued success of the squads perpetuated their lifespans considerably. After picking a fight with UAW leadership after moving the M and L body cars to Kenosha, and with the K-based AC body Dynosaur and New Yorker in the wings, Iaccoca decided to kill both elderly models. He announced early in 1988, that M-body production would cease that spring, and a rather substantial uproar commenced. All manner of threats and bets flew between the UAW and Chrysler, and even the State of Wisconsin. Iaccoca finally relented, and moved the end of production to December, when assembly would normally break for the Christmas holiday. Sadly, although the cars had been improved (a TBI system had been designed and readied for the cars in '86), sales plummeted after the first announcement. 5th Avenue sales dropped to around 40,000 units, Diplomat (all) sold around 11,000, and the Fury struggled to hit 5000. Chrysler abandoned the growing (at that time) RWD/V8 market, to sell yet another K-car spin-off. Yes, the AC/AY cars sold well. No, they were not superior to the AM. It would be 16 model years until RWD/V8 cars returned to the stable, and although the LX (2005-2010) cars had their flaws, they started a revolution in their market. By 2011, the new LD (2011+) Chargers had taken out the Crown Vic and Grand Marquis, and after 2017, the Caprice 9C3/ Caprice SS and Taurus. As Ford liked to say in 1997: "And then there was one..." as it will be Chrysler with the only American RWD/AWD/V8 sedans on the market. Something for us Mopurists to be especially thankful for !!!
