A friend of mine has a 99' Dodge SMB same floor plan. Bought it new and has had no major problems. I'm sure he has close to 150,000 miles on it.
I must say though that the interior on the one you are looking at seems to be a bit "ragged" out. They used a lot of Armour All in the cab and a ton of wax on the exterior but there is no getting rid of those stains.
With the low mileage and all those stains one would think that the only time they took it out is when they wanted to have a food fight going down the road.
Just my 2 cents. Can't help you on the price as I don't know what that model year 2wd's are going for. Check SMB's website for used pricing.
