You mean the cars from the 1st movie seen at the beginning of the 2nd movie?
For me these should only mentioned in comment, I do not think it is worth listing them as vehicles from the 2nd movie...
As these are scenes from the 1st movie, a link to the vehicle page of the vehicle from the 1st movie would be enough.
What do you think?
But if you want to list these anyway, good question: 1 or 2 stars... (anyway in the future there will be a separate rating for that)
