I have a 1965 Olds 98 4 door, 455ci that a bought from my father which he bought in 1965. It has 17200 original miles on it and has never been in an accident. Interior is fine, but needs some cleaning which I am getting done. It's being painted the original champagne color and all the chrome is in excellent condition. This car has never been in a accident. Everything works except the clock. Will be taking to local car show in Virginia beginnig next month. Car rides wonderful just as I remembered as a teenager riding next to my Dad.
We still have the 1965 Oldsmobile 98. I bought back in 1973 when it had 11K miles on it. My son has it now.
If yours has a 455 cu in V-8, somebody replaced it. All '65 Olds 98's and Starfires came with a 425 V-8, either 365 or 375 horsepower depending upon the cam. The 425 is a short-stroke version of the later, (1968-'76) 455 V-8, and has quicker pickup. '65 was the last year for the silky smooth responsive Rochester 4GC carb, (with 4-corner idle). 1966 up they used the boggy Quadra-Jet, which did offer a bit better mileage but poor response.
Anyhow the 98 still runs great but uses Premium fuel, (ultra high compression) so we drive a Lincoln Town Car to get groceries. It's a barely adequate substitute for REAL American cars, like the Olds!
My father had one of these when I was a kid. It was called a 98 Luxury Sedan 4 door. Blue with black vinyl top. The inside had wood grain panels, and hold handles in the back. It was basically like a limo, and drove smooth and quiet like riding on a cloud. Nothing like today's cars where you feel the bumps and the ride is firm. This was the best riding Olds of all that he had owned.
