Looks to be pretty darn clean and in today's market might just be worth the price even at 157k miles. It has been a tow vehicle though and I think Air Bag light is on.

5.9 or not, I don't see the price.

Why's the front bumper crooked? (subtle, but it is and it's not just the reflections, look at the gaps).

Driver's seat is all but pancaked.

Does the bumper have anything to do with the airbag light?

Looks good, not rotted, but just seems like too much for the mileage and probable use.

I noticed the driver's seat and figure a big person driving it. I'd probably recover/re-foam.

It looks like it might have been painted at one time. The engine compartment and underside are so clean though. I figure if asking $10k and took $8500-ish could be a nice truck for that. These are popular years for the Dak (for good reason) as you know I'm sure (before they got big and kind of ugly). Clean Title but I know that doesn't always tell a story.

These Dakotas have their quirks.
Airbag light probably a broken clock spring or possibly the ABS controller. The controller issue is age related, the clockspring is a common problem.
THe crooked bumper is a factory flaw. I THINK it is a mount flex/sag issue.
5.9 4 doors aren't easy to find. Always wondered about production numbers.
As far as Dakotas go this one hasn't seen a lot of sun.
Nice truck.
