I'm not saying it's not a legit business, but the "sc.pathmazing.com" subdomain is hosted separately from the main company website, and seems to be a rouge, hacked version of the original source.
Digging into this deeper, if you know anything about HTML source, just look at the source of each page.
HomeNet Automotive:
Code:
view-source:https://backwebs.homenetinc.com/tesla/details/@/5YJXCAE43JF106596/
Pathmazing:
Code:
view-source:https://sc.pathmazing.com/tesla/details/@/5YJXCAE43JF106596
Clearly the pathmazing link is a hacked, butchered up version of the homenetinc.com source page, and missing a significant amount of code and tracking. The pathmazing source even has some hacked code at the bottom from stackoverflow.
I'm not sure what's going on, but I can bet that it's not "official" and someone is using/replacing that link for some nefarious reason(s).
