I purchased my 2014 September 2021 with 21,870 miles on it and am at 35,300 miles on it now. Been 100% trouble free. So far I've put a lock box under the left side rear seat, did the fuse 21 relocation, new BFG K02 tires, swapped out all of the interior lights for LEDs, I've changed out the transmission pan for one with a drain plug, installed the extra capacity transmission oil cooler. Next up is a power steering cooler and possibly an oil cooler. I did have a pedal commander but I got the wrench symbol so I removed it and it's been about 1,000 miles and the wrench symbol has not returned.
Welcome to the club! You're going to enjoy the hell out of the Gen 1 Raptor. This is by far the best vehicle I've ever owned. I may have paid way too much for it but I am damn glad I was able to find a factory stock Gen 1 is fantastic shape!
