I searched and couldn't find a lot of answers for this but anybody know about getting temporary registration/buying an out of state car? This weekend I may be driving to NY from NJ to buy a car, only thing is I pretty much have to drive it back and the seller doesn't have it registered because he bought a new car. I'm also wondering if the DMV's are even open in NY on saturdays... I'm going with two other friends who are driving me there and all three of us work mon-fri so the weekend is the only time I can go. What's the process to legally drive a car bought out of state and legally driving it back into NJ?
