Hi Grisou29,
I am the co-owner of Off To Iceland, so I wanted to jump in and answer this personally.
First off, I honestly appreciate your skepticism. There are too many travel scams out there, and it is 100% smart to double-check a website that doesn't have a massive footprint yet. I would do the same.
To clarify who we are: You are right that we are a newer/specialized presence. The site was founded by Bjorn Steinbekk (you might have found him in your search—he is a drone pilot known for volcano footage).
We operate as a specialized partner. We don't just have random cars in a garage; we partner directly with established, major Icelandic fleets like Europcar, Rent.is, and Mycar to provide specific vehicles (often modified 4x4s and campers).
Regarding the reviews: Since we are newer than the big giants, we don't have thousands of TripAdvisor posts yet, but we are working hard to build that trust.
If you (or anyone else) is worried, please feel free to email us directly at info@offtoiceland.com. I’m happy to hop on a video call to show you we are real people in Reykjavik Iceland!
Safe travels,
Team Off to Iceland
