Mazda CX-7 VIN prefixes, and when each one was used
Every Mazda CX-7 we have on record, from 2007 to 2012, opens with the same three characters, JM3:

Where to find the VIN on a Mazda CX-7
A Mazda CX-7 VIN normally opens with JM3; the full number sits in four places, and all four must match.

| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |
