My 1987 Mercury Sable was a good car when I purchased it in 1997. It started for me every morning and was reliable just about all the time. All this ended at around 115.000 miles. The tranny started to slip. When I came to a stop sign, did a rolling stop and hit the gas, the car would rev to 3000 RPM and then bang into gear.
The A/C finally quit also, and the powersteering pump was leaking like it had a huge hole in it, I had to re-fill it daily.
I finally got rid of it when I was coming off the expressway and I was turning, and the wheel went solid.
I almost went right off the road. After that I got rid of it and bought a 1991 Pontiac Grand Am LE. And 5 days later the person who bought it off me for $50 came back and told me the transmission blew up, and the computer was messed up... other than that, it was a good car.
