Car Payment/ Trade in Question
 

I owe approx 10k.

Trade in value/ private sale is around 20-25k

Looking at g37 coupes around 20-25k

Not sure how the finances work as this is only my second car and my first one was paid off before i bought my Z.

Do I just trade my car for an infiniti as close in price or do I have to subtract what is owed on the car from the new price of my new car.

If someone could simplify my math or give me an explanation on trading/upgrading/selling when you still owe some money on your car towards the purchase of a new car.

PS- this is just an idea, not ready to trade yet, but contemplating due to personal lifestyle reasons with family and business and travel

Hypothetical round numbers.

You owe 10 on your car, they give you 20 for it.

You buy G for 25.

They will take 10 of that 20 and pay off your Z and the other 10 towards the G, so you will finance 15 on the G, plus tax tag and title, of course.

+1. Wat Mike said.
