Sure they are disposable. Not as disposable as a Hyundai. If you want a car that last forever get a Volvo. Their parts usually cost twice as much, right down to the spark plugs.
I always buy used cars for less than 2 grand. I don't have to spend alot on insurance, taxes and never have a car payment.They last 2-3 years so thats cool. Sure stuff breaks but I consider it a learning experince as I am not a gearhead but I do like spending the day in my driveway swearing at my car.
