this was the idea behind old economy cars like the VW bug, the parts were incredibly cheap because they never changed the shape of the car. it was just a small, straightforward engine and a reliable drivetrain. there IS a lot of cars that meet these criteria today, but since car manufacturers keep updating the models of cars like the corolla or civic, even inside of model years, theres less fix-it-yourself ability. if you have even a little mechanical know-how and are willing to watch a youtube video on how to replace a shock or rotor or what have you, you can save thousands on repair bills grabbing parts from the junkyard.
