Well, I was going to offer advice until you called my wheels ugly.
Just kidding.
I think 29 is steep. If I was you, I might play up the low tread and maybe look for a few other demons to talk them down on price. You won't get them far down, since it's only 11k mi. I might aim for 27-ish to 28-ish. I mean, the touring package is around 4k more expensive than base at MSRP, brand new. The difference after depreciation, you can maybe halve that, and I'd put a used base around 25. Then again, check cars.com or carmax and see what similar ones are going for. They're a better indicator than my estimation.
