Is this business / company legit.?

So I'm selling my truck on auto trader and I get a phone call from a guy in California. Now he states that his business is able to find someone to take over my car payments and there will be a contract signed that this guy, we will call him Steve, will be liable for the truck getting paid. Now here is the part that concerns me... The truck will stay financed with me but they will just send me money every month to make the payment. I know right sounds funny. So he gave me some company inf and I can't find any info on it, however there is a website but I'm still concerned. Is this legit and would you go through with a service like this? It's not subleasing, at least that is what the website states. ok here is the website www.servingyouwithcl.com
