Mine (2005 Damon).. if you are in the Driver's seat there is a small compartment over your head on the left wall. It's in there.. Might also be in a cabnet most anywnere.. If the unit has the original engine or tranny a Vehicle theft specialist (The Police kind) can likely find the engine/tranny number which though not the full VIN is enough for DMV to find it. IF that is they know how (I do but they may no.. It was part of my job for 25 years to know how. And I did).
IN fact there are other ways I know to find it but.. Thats in MI do not know about your state.
