buyonline.hertzcarsales.com is a subdomain that immediately redirects visitors to the main hertzcarsales.com website. That means you never actually land on the subdomain itself. For a car buyer, the real question is whether the main site is trustworthy. Hertz is a global rental and sales brand, so the parent company's reputation is solid. But the subdomain's setup raises a few minor questions: there's no contact information on the page, and the robots.txt file blocks all search crawlers, which is unusual for a legitimate business. On the plus side, the subdomain has a valid SSL certificate, enforces HTTPS, and includes privacy and terms pages. The legal entity disclosure ties it back to a real company. If you're researching is buyonline.hertzcarsales.com a scam, the evidence doesn't point to fraud, but it's also not a full-fledged storefront. Most established car sales sites have visible phone numbers and a web history you can check. Here, the Wayback Machine has no snapshots, which suggests the subdomain is very new. If you're considering buying a car from hertzcarsales.com, you should verify directly on the main site rather than relying on this redirect. The subdomain itself is likely just a technical convenience, not a separate business. As with any online car purchase, always confirm the seller's identity and payment security before handing over money.
