Looks nice and really the price isn't that bad at least what is being offered around here. I've seen diesels with alot more miles going for more than that. I even stopped and looked at a 97 that ended up only being a 2500HD single cab had a 350 in it with 287,000 miles on it and he wanted 4,200 for it, and it was a rust bucket.
I don't think it would be that bad to drive, my wife before wanted nothing to do with something so long but I think she might even change her mind a little on it as during the winter when my Daughters engine in her car blew up my wife was driving my Extended cab long bed and was bragging how she could get it into spaces.
