Well, this must be a new area code for Ft.Worth, as it turns out to be a Honda dealer in that direction. Apparently, my call to SERVICE triggered an IT glitch to SALES and they thought I'd left a message to inquire about a car. The salesman was very apologetic and assured me that he'd have IT look into it. I'm satisfied that it's not a scam, but I was unable to select a proper call type,  so will leave it as 'unknown'.
