This number is from Acura Fremont.

Thanks for that "No spam."  After I got text "I'm on my way" (from a person I don't know and have no plans with), I looked up the number.  After your tip, I realized that text came at same time as a msg. from Mazda Fremont trying to sell me a service plan.

Called my cell. Declined call since number wasn't in my contact list. Left voicemail. Fremont GMC wanting me to bring in my car for a managers special. I'm wary.

Called, no message left

Picked up their message on voice mail.  They are offering a manager's service discount on a car I previously owned.  Probably legit, but I am not calling back.  Given the Fremont GMC call listed above, this may be a telemarketing service working for dealerships or the two dealerships are connected.
