I don't know about you, but my 21st century car still needs regular maintenance and repair.
Yes, but does it need an oil change every three months? Plugs every year? Points? Carb adjusted when "it doesn't feel right"? Choke? Flush the cooling system? Replace the brake shoes (pad last far longer and stop better). Flushed the brake fluid? Replaced the automatic transmission fluid? Set the valve lash? Set the timing? Even fuel and air filters last longer today.
Everything that I've mentioned was maintenance - not repair. But repairs have gone down dramatically too. When was the last time that you replaced a dash lamp? Starter relay? Replaced a turning signal blinker? Replaced a dash voltage regulator? Replaced an oil pump? Serpentine belts last five times as long as the old v-belts. AC compressors last twice as long. Engines last twice as long and run better after 200,000 km than did 1960's engines after 2,000 km. Even water, fuel, and vacuum hoses last much longer.
