David,
For what it's worth (probably not much
), I think 100 LARGE is a big psychological barrier. Sorta like $4.99 seems like a much better deal than $5.01, though in a practical sense, there's not much difference.
Of course, by the time anyone actually finished the car, they'd be into it for significantly more than the cost of the roller anyway. But, some of us may find convincing our significant others of the reasonableness of a 100K purchase much easier than a 125K purchase.
Then again, the market in that atmosphere may be based just as much in exclusivity, as in perceived value. So, I suppose you'll have to make the call, and I've been of no help whatsoever (But, I hope you do choose the lower of the two...selfish reasons that they are).
