Model Year Differences?

[Biloff]

Well any 2004-2006 with flex fuel will always be a 5.7 engine.

GM stopped useing the 5.7 in 2000 when the changed the body style. 2000 and up came with 4.8 or 5.3. The 5.3 hybrid came out in 07 or 08. And of course the 6.0 in the Denali and Silverado HD's

If you have kids... not a huge deal.. but the LATCH system started in 03 as well...

This is actually a great point. My TrailBlazer was my first vehicle with LATCH and I'll never buy another vehicle without it. Super easy.

Yes, I have two, but I damn sure better be done needing a latch system at this point, or someone's going to have some expaining to do! Good point though if it might help someone else that stumbles across this thread.

The 03-06 do have some interior upgrades as previously mentioned and have a speedo that goes to 120 rather then 100. The 05+06 also came standard with electric radiator fans instead of clutch driven fan

This litttle bit of info is huge, E-fans FTW! Way easier to work on stuff, plus much less parasitic drag.

5.7 = obs noob!

personally... I would be looking for the tahoe/yukon thats interior has been taken care of better..

all of the differences between 00 01 02 03 04 05 06 are all minuscule compared to the interior and drivetrain condition.

DONT GET A 4.8... for gods sake

I have a 2001 Denali and it has a 120MPH speedo. It is Canadian originally though, so I can't override my running lights, they're always on.

The 03+ was better IMO. Double DIN is a huge plus, and the climate control is much better. E-fans are a very nice upgrade, I'm thinking about doing them to my '01.

I love my '01 Denali, wouldn't trade it for a '03 Tahoe or Yukon though. 6.0 FTW.

Yeah... that's not going to happen; that's why I was asking how to visually spot the difference, though I don't think anyone ever answered that. I think the e-fans really are a no-brainer, so '05 and up only for me at this point. Thanks for all the replies.
