Around 44 thousand km the water pump went on it, but it was only 50 bucks to replace. The reason the water pump went was I never check the fluid and run the bag off the car.
This car is the most comfortable car I have ever owned. It rides down the road very nice, has lots of power (does good smoke shows and brake stands), and still gets around 21 mpg.
It is extremely easy to bury the speedometer (140) and it beats most Toyota cars by 2 or 3 lengths.
I have driven the car across the country 3 times, I have nothing bad to say about the car.
I have owned two '85 Delta 88 Royals with much higher (250,000+) mileage and they last forever.. very comfortable and reliable, great performance. Only work I ever needed to do on them was routine maintenance.
"It is extremely easy to bury the speedometer (140) "
I assume that you mean 140 kilometers an hour.
My dad bought an 85 Delta 88 Royale back in 1987. It had about 45,000 miles on it. Ten years later he ended up giving it to me. I when I sold it the car had 215,000 miles on it. It was starting to show some age at the time. It was leaking oil due to some gaskets needing replacement. The a/c went out and the body was starting rust. Overall, that was a solid well-built car. It's such a shame all of Olds car were downsized the following year.
