If you haven't found a suitable rig, try the Austin Craigslist. If you find one that has been in the general area since purchased, it will be rust free. An ALPHA pops up on occasion and at a fair price. I drive a CE and my wife drives a 2008 X ALPHA with less than 50K miles that is like new, never been off pavement and all stock except for a MAGNAFLOW cat back. She has been approached about selling it but has declined so far. I recently sold my '09 YUKON DENALI that she enjoyed driving and has hinted that she might like a new one. If she decides to do that, we will probably try to sell the X.
Best of luck on your search!
