The benefits, feature wise, of the high country are HUD and adaptive cruise control.. and option for air ride which isn't available on RST. Otherwise, I don't recall any significant feature differences. But I like everything about the RST trim better as far as no chrome and black accents outside, the red stitching and the carbon fiber trim inside vs the wood trim. Also, I ended up really liking the RST wheels (would have wanted gloss black on any other trim but I feel the RST wheels give just enough contrast where gloss black might be a bit too much on a black RST). Anyway, I think for me it would be a tough pill to swallow to pay thousands more for the high country I didn't really want and then still have to spend more money blacking everything out, changing the wheels, etc. I'm with everyone else-- wait for what you want at these prices..
If you opened up to black paint, would you be able to find an RST w/ 6.2L at a dealer somewhere? Black seems to be much more common than dark ash when searching inventory.. I've stopped looking since I found mine but it looked like there were a bunch of others in transit a couple of weeks ago when I looked and maybe one of them isn't spoken for or maybe deal falls through on one? Just a thought, but if dark ash is a must have then wait for that too...
