Im looking to buy a 1989 gmc k1500 stepside z71. I currently drive a ford exploder and am looking to make the switch to a truck. I just need some tips on what to look for when i go to see the truck. I already walked around it and peaked in the window and it seems solid except for a little rot on the passenger front fender, rear bumper needs replacing, and the rubber under the widows is dry rotted. I did however notice moisture under the truck near the gas tank and it seemed to be wet from there to the engine. Keep in mind that it did not smell like gas and it rained the night before but it was greasy and everything else waws dry. The truck is selling for $2900 and i beleive has 125k on it any help would be appreciated thanks.
