If the IDENTITY column is used properly and not just as a row number, then you DO need to consider the joins because they will be mostly by IDENTITY. 😉

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Thank you, guys, for all the input, I was off work because of the snow and the kids were home so I have not had a chance to read the comments. I will read them and see if I have any further questions. My current plan is to keep the ID field and my current indexes because it is working fine.

Then I will probably make a copy of the table and try making the primary key the import date/Car Initial/Car number and see how that works.

Thanks for all the info and great resources.

Best plan yet. "One good test is worth a thousand expert opinions".
