Im sorry if this is the wrong section im a newb, so i can take some ragging on. Looking to buy my first diesel, i have an 04 Z71 extended cab right now, wife suggested we get a crew cab with the baby coming so i convinced her to let me get a diesel which ive been wanting but could never afford. I found some 05's and 06's i really like just cant decide which motor is better. I know diesels last forever from the motor standpoint its just hard to convince myself to spend around 20 on something with 100k on it. Duramax's are hard to find in my area (eastern NC) im stationed at MCAS New River in Jacksonville, NC. The ones i am finding are 05's and 06's with around 100k miles and pretty good options inside, they are priced from 19k to 24k. Just wondering if those are good prices and what i should be looking for when looking the vehicle over before buying. Im curious on what i should be feeling and listening for when test driving also. Im really good with gassers so im not completely incompetent on vehicles just very new to diesels and dont want to waste money on a "piece". Thank you in advance for any advice.
