I think $75K is a pretty fair speculative price point. My feeling is it will be higher for the first year for lots of reasons... dealer mark-up, dealer orders of only loaded trucks, etc. I'm sure if you wanted to wait a very long time by placing an order for a "base" TRX it might come in under $75K... but you're going to wait and wait.
I'm in MA, and you couldn't sniff a current gen Raptor for under $70K from a dealer earlier this year. I tried. I even discussed ordering one and the dealer wasn't interested. I wasn't to enthralled with the rest of the F-150 line so I moved on.
As comparison shopping goes, 0-60 times for a truck is just silly. Sure everyone wants to go fast, or compare stat sheets, etc... but thats not what it's really about, as others have noted above. The "value" of a TRX is similar to a Raptor... I'd agree there. They are both a kind of "Halo" vehicle. Very specialized and focused. I do think the TRX will be much more about the smile it puts on the drivers face than all out off-road ability, which will favor the Raptor a bit. The Tesla truck? I'd be really surprised if anyone who's seriously thinking of buying a TRX is going to hold off until the Tesla is a reality. Complete opposite ends of a spectrum.
