I keep my cars for a long time. My main needs are as follows. I will not sell my 2003 for a less reliable car. Reliability is key for me. I have taken care of all the idiosyncrasies in this car myself. I know the vehicle better than I know my wife. Scary I know but i know what to expect. I know every hiccup.
So...
1) Reliability is number 1
2) Currently my z71 has about 285 HP. I understand the 5.3 now has up to 355HP and the newer transmissions help the engine with torque. Not sure if I need the 6.2 liter. The boat weighs only about 5000 LBs. The 03 Z71 is enough but barely. The boat pushes it around some when cornering and coming to a stop. Something I didn't feel before this new boat. Not a big deal but if I purchase, I don't want to feel the boat anymore.
3) I keep my vehicles for a long time. I learn them and repair them myself. So I will be spending about $30,000 or so on the next used one once a good deal comes along.
4) I am a little reluctant to sell my 03 for a hunk of expensive metal and leather that dies on me on my fishing trips. I have heard and read stories in these forums that makes my less confident on this move. Hence why I am writing this...
Thank you and I forgot to mention, definitely (non-full time) 4-wheel drive.
