New, the Imperials always had more features than the comparable Cadillacs. They were also more expensive. Today, there are many Imperial clubs (I founded one - left it, then re-joined. At one time (single) I owned 6 Imperials.
I recently found one long lost on the web, in Osolo Norway!! Still a trophy winner, looking great! ('68 Convertible).
I don't know what else to tell you, so ask. I wrote a book on Imperials, that was published, and for which I won the very respected "Golden Quill Award" for Automotive Journalism. My family owned & drove Imperials exclusively, from 1957 until 1978, we got a new one every single year. There were beginning in 1970 always 3 Imperials in our driveway, Dad's Mom's and mine.
We never had a "bad" one. Many modern day automotive inventions were first on an Imperial !
Swevel Seats on the 1973 GM intermediates first on Imperial in 1958.
First Auto Dimming Mirror on Imperial
First Treansistorized ignition on Imperial
First Headlamp washers & wipers on Imperial
First Tubeless tires on Imperial
First No Tube Radio on Imperial
First Platinum Tipped Spark Plugs on Imperial
First 8-Track
First Cassette
First (and only) in car Cassette Recorder!
Only car to ever have the Federal US Government access a jewerly tax on a car, as their emblems were so finely minted, the US Govt. declaired them to be Jewels, and not emblems.
In 1958, the Queen of England came to America on a visit. The then President (I think Ike) asked her what she'd like to take home with her from America, and she said, "An Imperial" and he gave here an Imperial Limousine.
and on and on and on. List I have list 81 firsts.
People who are into them (warning here) are HARD CORE to the bone. I am different. I appreciate all cars, love all cars (especially AMERICAN ones) !
PS: The Imperial you speak of - from your description is a 1964. Did you notice the "eliptical" Steering wheel, semi square (or flat) at the bottom ??
