Hey guys, new to this forum and this is my first post. I've recently decided to purchase my first truck and I'm looking at buying a 2009 Sierra 1500 Sle Crew Cab. They're asking for $16,995 with 163,000 miles on it. I've been doing some research on this model and others and trying to figure out if its a good deal. It seems a little steep to me and I'm worried about the lifespan because of the high miles. I'm trying to find info on how many more miles on average people are getting, what problems I might run into, and really just any info you can share with me about this vehicle and if this is a decent deal. Thanks in advance!
