It would be similar to;
Hey, anyone know Lisa? I would LOVE to get in touch with her, I have not seen her in years!
The first thing anyone would want to know is Lisa who? I know several girls named Lisa.
So, in this case, the BS23R0B is the first name & the 199592 is the last name.
Anyone who is serious about locating something for their car in a 'wanted' thread like this one should post the full VIN or it is a waste of their time.
A point to consider, hypothetical situation.......
Bob finds a broadcast sheet for BS27R0B555555 in his car. It does not match his car, so he does a google search for BS27R0B555555 & no matches are found.
The car still exists, but the owner posted a want ad & just used BS27R0B555xxx. Bob is not going to search for that, so he will not find the owner of the car.
It is the owners loss, so close but no cigar.
Another common mistake that some posters make is using the letter O vs. a zero. Our cars will not have any Os in the VIN, so make sure you get it right if you post about it to increase your chances.
Best of luck to anyone searching.
