A headlight of 83-year-old Oscar Almaguer's 1967 Volkswagen Beetle is seen in Apodaca on the outskirts of Monterrey September 11, 2013. Almaguer has lived in his car since he and his wife divorced ten years ago. The maintenance that has been done on the now 46-year-old Beetle is basic and few of the car's parts are original. The engine, which Almaguer starts by short-circuiting two wires under the hood, comes from a more modern VW Sedan. The wheels and seats are from another Volkswagen model and instead of a gear-stick Almaguer uses a plastic bathroom pipe. The company behind the classic car model which Almaguer calls home is on the up. Volkswagen said on October 30, 2013 that third-quarter operating profit rose by a fifth on the back of record sales at premium brands Audi and Porsche, keeping the carmaker on track to meet full-year targets.
