[FIRST NAME],

I was looking over our records and wanted to immediately send you this note regarding your [YEAR MAKE MODEL]. We have been tasked with buying as many good, clean, used [MAKE MODELS]s as we can for top dollar, but we only have this weekend to get it done. As the General Manager I am authorized to offer you as much as $4,000 more for your [YEAR MAKE MODEL] if you upgrade your vehicle with us.

Please call me directly to set up an appointment.
