Since Thrifty is selling you miles at about the same cost (maybe even slightly more) than you can buy them directly from the airline, that's not a good deal.
Rent at the right times and a 16 rental days will cost you no more than $200. That credit can then be redeemed for a peak-season rental worth $100. Getting in effect 50% cash back on you rental cars seems like a pretty good deal to me.
