I got a slew of voicemails warning me of an "urgent" issue with my alleged extended warranty - which of course I knew I had never purchased. After five or six calls, I became impressed with their persistence, and actually returned a call. They had the correct make/model/year, which got me curious as to how they got the info. The easy answer is that the dealer simply sold the info, being as how you sign reams of paper when you buy a car, they could have easily slipped a statement in there somewhere. Or, are Oklahoma DMV records easily searchable to list recent new car sales and registrations? I even read a claim that some states sell the info. Anyone got any insider knowledge?
