Looking for advice/guidance

Have a car bought used 2 years ago transferring $10k negative equity into the loan, now in a situation where the car is too small for our family and looking to up size but not sure whether to transfer current negative equity into new car loan or to pay it out over the term of a lease. Let me know, advice is greatly appreciated, thank you.

Car Worth/Value now - $20k Car note/owe - $33k

Have $10k to put down
