We're glad that most people don't wait 33 years to buy their first Volkswagen.       But Albert Gillis did, and maybe he had the right idea all along.       He didn't buy a new car for 33 years because he didn't happen to need one.       He and his 1929 Model A Ford did just fine by each other.       He always did his own repairs and even jacked it up at night to save the tires.       When he needed a new car last year. he went out bought a Volkswagen.       "I heard they hold up," he explained.       Does he like the VW?       Mr. Gillis is 78, a Justice of the Peace, and not given to hasty decisions.      "Your inspectors sure do a good job of inspecting," was as far as he would go.       But he did mention that he and Mrs. Gillis took a trip for their 54th wedding anniversary.       They drove 6,750 miles and spent just $62 on gas and $0.55 on oil.       "I didn't think they were supposed to burn oil," he said.
