I had a guy respond to my car for sale add, named Larry Herr, I sent him another car report but he was insisting on cardetailcheck, saying it is much better than all the rest. He built up to this with legitimate questions about the vehicle in previous emails. When I went to the web site, DuckDuckGo wouldn't even open it and had a D grade next to the address. It sounds like a scam to me too.
