Wasn't really sure where to post this, so I'm starting here. Found an '02 Silverado 3500 Crew Cab DRW loaded in what looks like excellent condition on the Southeast coast with 75K on it for just shy of $19k. Appears to be mostly stock. Add says budget buy sold as is. KBB and NADA show it for around $16K. Are they out of line? I'm waiting to find out if it's had the injectors worked on. Any other things I should look out for? Would you be concerned with the salt water in the area? Thanks for any advice.
