I've been looking for quite some time...
Here are some average examples of what I see daily. Been looking off and on for about a year.
http://www.ksl.com/auto/listing/1044530?ad_cid=1 <-- 2006 White DC auto TRD 150K $19,500
http://www.ksl.com/auto/listing/1042271?ad_cid=9 <-- 2007 White DC auto TRD 96K $19,500 (I know the guy that's selling that one, he won't come down anywhere near $17,500.)
http://www.ksl.com/auto/listing/1040576?ad_cid=12 <-- 2007 Silver DC manual SR5 110K $22,000 (accidents and form the rust belt until last year -Carfax.)
http://www.ksl.com/auto/listing/1001281?ad_cid=5 <-- 2007 red DC auto SPORT 117K $21,000 (repo from east coast auto auction - Carfax.)
There are some that are way out of line,
http://www.ksl.com/auto/listing/999196?ad_cid=8 <-- 2007 DC SPORT "ONLY" 199K miles, $17,900
The thing is, I'll have my eye on one like any of those top 4 and they sell within the week. The TRD DC's are just crazy expensive... Ex cabs aren't so bad, but I need 4 doors.
Come to think of it, I've checked the carfax of tons of east coast auto auction trucks... Maybe it's because they sell for more in Utah? Guess so...
