Copy the first 5 data, insert back and set new VIN values for copied data, id will be auto-increment

Answer

If id is an identity or auto increment column (or something comparable), you can use:

insert into car (vin, car_name, mileage)
select vin, car_name, mileage
from car 
where id between 1 and 5;

Not sure what “update the VIN” is supposed to be though.
