Craigslist seller is dishonest?

A guy is selling a car I owned a few years ago. 1991 Ford Crown Vic. He's blatantly lying about the mileage stating it has 62,000 so he's asking $2500. It has 162,000 because when I owned it it had 128,000. The guy would know this, so he's trying to get way more than the car is worth. Now I know for a fact this is my old car as there's not many of those in my town anymore and it's the same color body, the back bumper had damage when I had it, the front headlight assembly was replaced which that's still there.

It's not my business to interfere but I'm just trying to prevent someone from getting ripped off for this guy. I sold it to him for $700 so he knows what it's really worth. No engine replacement or rebuild was done to it, he said it's all original. Aside from flagging his ad is there anything else I can do to help buyers from falling victim to this guy? Oh yeah and the odometers in them days only had 5 digits so once it rolled over from 99,999 it went back to 0. There's no way a buyer can see it really has as much as it does.

Legally, mileage doesn't matter on a car that old. It would be exempt on the odometer statement.

When you sold it to him, I'm assuming you put the mileage on the title? If so then the DMV should have issued a new title to him with that mileage on it.
When he goes to sell it the title should have your mileage on it and hopefully the buyer will notice that and will cause some red flags to come up.
Another thing you could do, anonymously of course, is to put something in Craigslist about people checking out the cars they are thinking of buying. Don't actually target him and your old car, but a general kind of posting. Maybe the new buyer will take the advise.

Does your state have list miles on the title. Ohio does so if even if the car has a 5 digit odometer when you sold the car the title would say 128,000. So the buyer would see this on the title. If they do not look at it then that is their mistake.
I see what you are saying here, and sure you are thinking about someone buying a can getting cheated, which is cool, but a few points.
1. It is not your business. Does this guy monitor your activities, see if you break the speed limit, leave work 15 minutes early when the boss is gone? Not perfect examples, but you get my point.

2. From a practical perspective. The buyer of a car is responsible for checking the car out. Everyone knows this. The Ohio BMV web site has a list of tips for used car buyers. Most people buying an old car understand a five digit odometer is turned over 100k. And even a novice would see the wear and tear on the car and know that it was driven more than 2,600 miles a year. Also, any mechanic will know the car has 162k miles on it.

3. Are you going to do ongoing monitoring of this guy. What if next month he lists ' a '78 beat up Caddy for $20,000 and says it was owned by Elvis?
