full_context: Document 1: Volvo S40: The Volvo S40 is a compact luxury car marketed and produced by the Swedish manufacturer Volvo Cars from 1995 to 2012 across two generations.
Document 2: Volkswagen Golf Mk3: The Volkswagen Golf Mk3 is a small family car, the third generation of the Volkswagen Golf and the successor to the Volkswagen Golf Mk2. It was launched in mainland Europe in August 1991, in the United Kingdom in February 1992, and in North America in the spring of 1994. The delay in North America was due to Volkswagen's decision to supply U.S. and Canadian dealerships with Mk3 Golfs (and A3 Jettas) from the VW plant in Puebla, Mexico. Quality control problems led Volkswagen of America to reject Golfs and Jettas from Mexico; shortly thereafter labor unrest at the plant delayed production there even further. The third-generation Golf and Jetta first appeared in North America as 1993 models in the San Diego, California area and in Canada, then in the autumn in the rest of North America as 1994 models. The Mk3 Cabrio replaced the Volkswagen Cabriolet, which continued the original Golf until 1993, although the original Golf, sold as Rabbit in the United States and Canada ceased sales in 1984. The Mk3 Cabrio continued until the 2002 model year, when Volkswagen replaced it with a convertible version of the Volkswagen New Beetle. The Mk3 was sold in Japan alongside the Polo, where both vehicles were in compliance with Japanese Government dimension regulations that encouraged sales. A 1993 UK advert featured the Bluebells song Young At Heart which resulted in a 4-week spell at Number 1 thanks to the popularity of it.
