I'd take a used top of the line coach with the same book value before a brand new entry level. Like said, engineering and quality doesn't go away with age, but if it's not there in the first place, newness won't help. Maybe with some standard things, but overall, not worth spending extra money.
Now, even if the book values match, the older unit is worth more. Reason being, the depreciation leaving the dealer's lot and whereas the used value should stay the same. In our case, with what we paid, the low book value is still better than 10% higher, more than a year later and retail even more so. Not that retail counts for anything, unless you're a dealer and taking a trade in to make things look good, but just saying for the sake of numbers.
