I get the math on resale, I do but what fascinates me is that not one resale person ever factors this into their math. Resale could take a year or longer to find what you want. Finding the right contract, having the offer accepted and then passing ROFR takes at a minimum 12 weeks. Don't pass? Start over. Say you take 1, maybe 2 trips during then that you pay cash for and you stay deluxe cuz that's how you roll, now how much have you really saved??? Buy a stripped contract and even less.
Basically anyone can make the math work in a way that makes them feel good about how they bought and that's ok with me.
