Im looking at a 02 GMC 2500 with 167,000 miles, seems to run strong and no smoke that i could see. The trans has a little more rough of a shift from a stop and into second than other D/As i have driven but barely noticeable. Does this sound like a concern. Its adn ext cab 4x4 no bells and whistles, he is asking $15,000. Can anyone convince to buy or not to buy???

Been trying to get a D/A since they came out, new is just too expensive for me.
Thanks to anyone with imput.
