You can do that just be aware that you will eventually be spending more than just buying a new car just to keep the current one in good repair. Car collectors get around this because they use have a different car as the daily driver, and their collected car is repaired and only used in parades and such.

You are also turning away a lot of the advances in electric vehicles. Paying for gas in your old car, could be more than payments on a brand new electric car. (that would require a lot of driving.)
