So as a current 2020 Raptor Owner, I’m a member of a Raptor Forum. I started a thread on how the TRX may impact Raptor resale value (I hope not a lot, if Ram does the TRX justice I’m a buyer), and now I put a copy of the build sheet up. It‘s kind of fun to poke the bear!
There is no way Raptor sales won't be effected by the TRX. Even if only slightly. Up until the TRX, Ford cornered the market, but soon there will be the TRX as an option. If they offer the 392 as well, it will make it even worse for Raptor. I see their values falling most definitely, especially on a 2020 that takes the initial hit as soon as it leaves the lot.
I'm in the same boat (sort of). I'm considering trading in my 19' Redeye in for the TRX. I know (especially with power dollars), I will take a hit. How much of a hit depends on if I will go threw and get one. I live in the Northwest (looks like you do too!) and I tire of only being able to drive my Redeye 6-8 months out of the year. I could drive the TRX all year long if I wanted to and take it places we have in the Northwest that my Challenger simply can't go. Plus I've been wanting a truck to pull some toys around (atv's, side-by-sides, etc).
So if the TRX truly starts at just under $70k, I'll be a serious buyer!
