You got it, it’s a 1990 Thunderbird
1948 Oldsmobile? I’d say Series 60 but models back then were basically what would now be different trim levels.
Don’t let the picture fool you. It is originally a pre war car that got an extensive post war facelift, so this is probably the most modern looking part on the whole car.
The model name was first used in 1939, and for most of the time this was the top of the line model from this manufacturer. However, when it disappeared in 1970, it was the lowest trim level of this manufacturers largest body.
Cadillac Series 61?
Yes, 1951 Opel Kapitän.
126 then? Though I doubt it…
Chevy Camaro 1st gen?
