I drive a like new 1988 Pontiac Firebird I paid $2000 for. It has a new engine, trans, fuel pump, tank, and a slew of other new parts. There is absolutly for me no reason to ever need to really sell it other then if I need money or find another hellova deal. You dont need to always buy new all the time you just need to know cars and parts/repair costs if you do the work yourself or have someone else do them. New cars break just as fast sometimes as a used one you may pick up. Granted you got that warranty but if you take my car for instance if it breaks (majorly) a engine rebuilt is $500, tranny $500, rear end $200 why would I even if a new car comes with a warranty spend $15k+ when if it breaks out all at once Im looking at under $3000 with parts and labor and another 100K easily. All else that fails is maintanace since my car reall yhas no real computer controller crap to speak of. And if the engine thows a rod and needs to be replaced Im striping the computer crap out and putting in a carb'd motor.
It is crazy how some people think having a warranty is the only way to go. I been buying and selling cars since the age of 14. Im now 34 and have owned over 400 cars in my lifetime. Some of which I paid $25 that ran and drove and needed no more then brakes and a tune up and no more paid then $8000 on a van I traded in for a 98 Jeep Cherokee with Inline 4.0 6 banger with 91K and a 97 Taurus SHO I turned right around and sold for $3500 and bought the Firebird. Other then that the majority was never over $800.
You dont need new, no point. If you dont know cars there are services that do and will check out anycar for you for a small fee. But buying used or if warranty is a must have you can buy a extended warrantyon almost any car including at the time you buy your new one. IN fact OP call the dealership you got your car at. As long as your still under the factory warranty you can buy and extended which would be much cheaper then what you thinking of doing.
And BTW rolling over into anything else is going to screw you for years to come because that roll over you will never get away from, EVER, for a car depreciates and the roll over will just keep that used car at a figure you will have no choice but to keep it till its paid off. And thanks to the roll over you will have to pay atleast more per month or more total months and by the time you get close to paying it off your "warranty" will be far gone and your stuck with a super high milage car, worth way to much you cant get out of it, and if it decides to break on you, at that point your looking a mega bucks repair bill and still have to make your payments on it including insurance.
Again why I drive a old GM where parts are a dime a dozen, cheap, and easy to fix myself.
And BTW this is my car. Doesnt always have to be brand new to have something good 😉
