Okay, so the 2005 loaded Tahoe was too much $$ for what I would be getting, dealer questionable etc... Maybe my price range is better served in the 2004...what's the difference between the years 04-05? Read something about "piston slap" in the 04's...what the heck is that? Seems from this forum that the mpg is about the same for both yrs. So I'm still in search of and trying to compromise...
