Now that I have seen the ad, I question whether the car described is the same one in the pictures (which look VERY NICE). the copy says '5 speed manual', but the picture shows an automatic I believe gen 2 Pony's came with a lighter duty alternator, henceforth no A/C or rear window defroster. A previous owner of ours put in an entertainment system that pushed 100's of watts and part of the system was a 'normal ' alternator. If you want to know if an Escort has 65.000 or 165,000 miles, just listen to the speedometer, one with 165,000 will be a lot noisier than one with 65,000!
I'll 'fess up right now. Our Pony's speedo is quiet because when I replaced the interior the speedo was already loose so I pulled it out and gave it 2 very small drops of XL synthetic medium model locomotive oil. At the time the mileage was about 220,000, but I can't see a dealer going through the trouble of doing this.
