I could not take that interior color! I don't know if the reason why there are so many of these 78/79's with low mileage is because the owners believed these were the last of the Big RWD Chryslers, or if the Horrible Lean Burn Ignition systems self limited the Mileage like the 78-83 Carb'd Buick Turbo's.
The LeanBurn system is easy to bypass, with a new Chrysler Electronic Ignition system (distributor, ECU and harness), and using a non-LB carb. I owned a '79 New Yorker for about two years - great car! 360 auto, leather, loaded out. The seller is whacked at that money, though! Oh, wait, it's Barrett-Jackson week, that's why!
