hi im new to this page and forum and ill be searching around for my answers i have but this time i just need quick answers. i bought a vw dune buggy /sandrail where can i find the vin on the frame of this thing any help would be awesome. thanks

Maybe others can help. As a sand rail it could be anywhere if it's there at all.
I've seen sand rail frame kits w/o numbers. Has it ever been titled or registered?

That rail appears to be a Berrien frame. Unless a VIN was applied to it by a state motor vehicle department, there will NOT be one on it. Berrien and other rail frame manufacturers do NOT assign VIN numbers. They don't make complete ready to drive cars for the street. Registering for the street a rail frame which has been put together with parts from other cars can be negotiated between the owner and the state DMV. But the frame builder is not involved. Some makers apply a serial number to their frames. That is legally quite different from a VIN.
