<prompt> Human: my transmission on my murano just died. 4K to repair, 150K miles - its time for a new not brand new car. However, I am in a rush. I dont have friends with extra cars I can borrow and I have a son that I have to drop off at schooletc. I want to limit the amount of days I rent a rental car, as those costs accrue as well. I would like to purchase a car by Tuesday it is Saturday nigh now. On top of this, work is crazy, my son has obligations I cannot cancel. I have limited limited time to make a decision between now and Tues. Suggestions? best practices? Lease? own? 3K available for downpayment. trade in value for my car will likely be shit 150k murano with a few dents on side and failed transmission  <response>: Dont let the dealer know youre in a hurry and need something badly.
