Thanks Brad, Pin and Rappa,
Let's take some key points here:
The XT\Skyloops still appear on the website, and as stated, they'll make anything for the right price.
The manufacturer will continue to provide support to existing customers regardless, for the reasonable life of the product.
These weren't my only points, as Joel's original arguments also stated that "Maurer no longer makes any rides that contain: 1- X-train 2-Lap Bars 3-Vertical Lifts" and through the direct website info, I showed that their options continue to include vertical lifts and lap bar restraints.
Gladly, he provided the full screenshot of his ridiculous email, and judging by the timestamps (posted Saturday, received "yesterday") he's only emailed them to confirm after I've called him out, so it wasn't information he had to hand when he made his original assertions (on Thursday).
Finally, his full name "Joel Ottaway" has lead me to connect the dots that he is Troy Ott (away) A.K.A. @totta3 A.K.A. @Minions! very dumb, stupid, annoying younger brother.
Knowing the Ottaway family history on these forums, it explains everything.
