I had a 91 2.3 that only had 60k on it when I bought it. (1998-2001) I got in the low 20's at best on the freeway. I always ran 80mph tho. I got 18mpg around town. It was not the fastest car out there but I thought the 2.3 did great on the freeway
She wanted to run 100 all day. I remember in hot ga summers she would always run a little hot with a/c on and I would get nervous if I ever got stuck in traffic...Great little car tho. Only issue I had in the 3 yrs I owned it was one bad shock and the leaky a/c. I had to charge it every 2 weeks in the summer. I traded it in with about 80k on it for a used Explorere Limited in 2001. They allowed me about $6k for it back then. I had looked long and hard for a nice 2.6 but out of the 3 I test drove and seriously considered all had bad oil leaks from what appeared to be the rear main.
