They are gonna repo my car!!!

Hey quick question for anyone. I owe a bunch of cash on a piece of crap car. I was wondering if I got another car and decided to stop paying the other one, Can the loan company do anything to my new car? Like try to force me through the courts to pay off the old car at the risk of taking away my new one. I am not worried about my credit. #ty anyway, but better than when I got the old car. My interest is more than the payment.
