Seems like IX's still go for quite a premium. Just for your reference I found my IX MR in September for a decent deal I thought, 44k miles, only has intake, exhaust, boost controller and tune, for $21,500. I talked the guy down from $23,500. I would say mine was/is probably about a 9-9.5/10 as far as overall cleanliness. One small scratch on the front bumper, a little pock mark in the dash board, and I had to replace the shifter cables when I got it ($80 and about 2-3 hours), but the price was right and it was local, so I jumped on it.
$28k for a IX??? That guy is on crack even if it does only have 9k miles.
This would be a much better buy IMO. a few guys here have ridden in it/seen it also.
