Tough to see in the pictures but the top on the deVille is dark green, the interior is matching dark green nylon.
There is some amusing family history with the car. My Dad liked his cars loaded with every possible option. Uncle Jerry's Caddy is very lightly optioned. Doesn't even have power locks or cruise control. When someone would make an admiring remark about the Caddy Dad would refer to it as a "Glorified Oldsmobile".
Dad had interesting cars when I was a kid. '60 Plymouth wagon, '59 Imperial, '63 Imperial LeBaron, '66 Imperial pale yellow with green interior, '70? New Yorker sedan, pale blue/dark blue '72 New Yorker coupe. That car stayed in the family for about a decade, became the "second car", then my brother ended up with it. I will have to hunt around to see if I have any pics of these things.
I really like the big stuff and I still have a huge car, but it's not a Mopar. My '69 LeSabre I have owned for 37 years!
