People who didn't know what a Raptor was by 2014, still don't. They don't pay attention to the "spotlight" of the automotive world and it's just a F150 with some big tires to them.
I really think both trucks stand on their own way more than you think. Lets go back a few years and compare some other high end Ford specialty vehicles shall we?
A 2003 Cobra had a MSRP of approx $34K. One with 20K miles in great excellent condition books at over $23K now. $11K depreciation. It still commands 70% of it's original MSRP. Very impressive for a 14 year old car.
The "next Cobra" was the 2007 GT500. MSRP was approx $41K. One with 20K miles in excellent condition books at almost $29K now. $12K depreciation. It is also worth 70% of it's original MSRP, again very impressive. Compare both to any Vette from the same years...
So the older 2003 chassis with less power still is worth the "same" as the newer 2007 chassis which is safer, has more power, better handling, better brakes, etc. It even has the Shelby name attached (literally), yet comparing new vs used values- it still has no additional value compared to the 2003. The GT500 is also not saddled with a horrible sounding engine either- both have blown V8s.
You guys can mock all you want- but remember that hearing is one of your five senses. Smell and taste don't count when it comes to vehicles- so you are taking away 33% of the "experience" of driving a Raptor when you take away the nice V8 melody and replace it with V6 *blat*. Ford knows this- that's why they tried to fake it with the stereo system.
Hopefully you don't view your mass produced G1 as a good place to store your money. It's a used vehicle and prices will fall. I'm sure there will be a resurgence at some point like there has been for the older Broncos, but it took 30 years for that to happen.
