Browsing through CL, I see this:
1986 RAM. 318 CI., auto, 28K orig miles,(not rolled over) shines shines shines. Body, mechanically very good cond. interior looks new!
6' bed, 2WD.
Going to see it tomorrow.

 

in ontario that would be around 5,000 as in no rust at all and clean
emmissions

 

In the States you should beable to pick it up for 2500 or less atleast I wouldn't pay over that anyway

 

I've seen a LOT of "low mileage" cars and trucks from that era that have over 100,000 miles trying to be passed of as less than 100K miles.

My check list:
Check the turn signal lever for rotational play. They loosen up around 75K miles.
Check the brake pedal on the right side for wear. It should show a very minimal amount of wear but should not be brand new in appearance.
Check under the dash for dirt accumulation. Nobody cleans under there because the average person never looks there.
There should not be any cracks forming on the drivers side edge of the seat where they always crack around 100K miles.
The carpet retainer sill plate molding on the drivers side should have some light usage scratches. The screws should have a light accumulation of dirt around them in the form of a light dusting.
The glove box door should still function like new. It should not be bent, straightened or operate differently than when it was new.

These observations are based on the appearance of my 1970 Dodge Challenger that has gone 28,000 miles since we bought it brand new.

 

I appreciate the last reply. But no figure was provided.
There is no "book" value on this year. I do know that if this car were to be traded in to a dealer against a new purchase it would be worth ~$500 to them (more times than not, just a token of observing a trade) not of real value to them.

 

Dang, you are sitting on a gold mine brother!

 

Here in the desert southwest there are still lots of these trucks running around in nice condition. I've looked at a few that have appeared on craigslist and paid the fee to run the Vin through carfax. Two out of three times they came back with 100 or 200K more miles. Here one can't underestimate how much indoor storage does to keep a vehicle looking new. The one that was an honest, low mileage vehicle (std. cab 1/2 ton), they would not budge off of 8K and it did not sell on ebay nor craigslist even a year and a half later. So I'd say it's worth whatever you can sell it for on the day and time you want to sell it. I have always looked at it as what do I value it at. Could I replicate the condition for the same price I'm paying. I'd also argue that if your considering paying a premium for a nicer older truck do all you can to confirm its value to you.
