In 1988 I inherited my Grandparents 1965 New Yorker. A big car, very smooth ride, huge trunk.
That is the end of anything positive about it. Had a 383/Auto. Gutless wonder. It could cruise all day at 85mph. Which was a good thing, since it would take all day to get there. I was almost rear ended several times , by Semi Trucks when merging onto freeways. I'm not kidding, it would take 2 or 3 miles before it hit 65. I rebuilt the carb, couple of times, played with the timing, blew out the fuel lines, changed the fuel filter. Did everything I knew and took it to a couple trusted mechanics the Horseless Carriage Club. They were older guys then, and nothing they did could make it run any better. It had no 'miss',did not surge, just accelerated at a painfully slow pace. I sold it after a couple of years. It was just too frustrating to drive. In Town, it had no problems. It was only on the freeway that is had troubles, but I did a lot of freeway driving back then, between my apartment and my parents house.
