Tas if you paid 4500 for something that lasted a year you got a bad deal. Really bad. Unless it was a Corvette and hopefully you enjoyed it. BTW buying used leases are usually the worst since most lessees don’t take care of the car. No oil changes no maintenance, and drive it like theres no tomorrow. So not great.
Best is to buy only from a private seller usually they are upgrading or the like. Dealers are charging you much more than the car is worth and will totally lie about the car issues just to make that profit.
