Assuming you may not be preforming your own maintenance - find a close local shop for
oil changes, etc. Pay the guy and extra hour of labor and do a full car nut and bolt check (on a lift) at every
oil change/visit. Well worth the money. Pay close attention to all half shaft bolts, suspension bolts and brake bolts. Check every bolt you can reach. Change the fuel filter once a year. Check the timing often, and check the dizzy gear and springs every year. Also make sure you are making enough vacuum to run your brakes.
