Hey everyone, I'm looking for a little direction... I just got a 2005 V8 Silverado ext. cab from my father in law, it has about 175k and runs like a champ. He took care of it, regular maintenance and such. I'm just wonder what kind of work/maintenance I should have done so I can get as much out of it as I can. Also wondering how many more miles I can expect to get out of this truck. I have about $1500 to put into her. Thank you in advance!
