The Ducati SportClassics were a range of retro styled motorcycles first introduced by Ducati at the 2003 Tokyo Motor Show, and put on sale in 2005 for the 2006 model year.
 The Paul Smart version was made for the 2006 model year only, while the Sport1000 ran from 2006 through the 2009 model years, and the GT1000 ran from the 2007 through 2010 model years.
The Pontiac G8 is a rear-wheel drive sedan that was produced by Holden in Australia, and then exported to the United States, where it was sold by Pontiac.
 The G8, a rebadged Holden Commodore, was released in early 2008 for the 2008 model year in the United States, and in 2008 for the 2009 model year in Canada.
 Production stopped in mid-2009, following the GM decision to suspend the Pontiac brand.
 While available, the G8 took the place in the Pontiac lineup of both the Pontiac Bonneville, which ceased production after the 2005 model year, and the Pontiac Grand Prix, which ceased production after the 2008 model year.
 The G8 was Pontiac's first full-size car since the Bonneville and the GTO coupe last sold in 2006.
The SEAT Toledo is a small family car produced by the Spanish manufacturer SEAT, part of Volkswagen Group.
 The Toledo name was first introduced to the SEAT line-up in May 1991, with the fourth and more recent generation being introduced in late 2012 as a 2013 model year car.
The Grand Prix was a line of automobiles produced by the Pontiac Division of General Motors from 1962 through 2002.
 First introduced as part of Pontiac's full-size car model offering for the 1962 model year, the marque varied repeatedly in size, luxury, and performance during its lifespan.
 Among the changes were positioning in the personal luxury car market segment and mid-size car offering from the 2nd generation to the 5th generation for the sedan and from the 2nd generation to the 6th generation from the coupe; it returned to a full-size car from the 6th generation to the 7th generation for the sedan, positioned below the larger Bonneville in Pontiac's model lineup.
The Cadillac CT6 (short for "Cadillac Touring 6") is a full-size luxury car manufactured by Cadillac, first introduced at the 2015 New York International Auto Show and first sold in the US for the 2016 model year.
 It is the first car under Cadillac president Johan De Nysschen's leadership to adopt the brand's revised naming strategy, as well as the first rear-wheel drive full-size Cadillac sedan since the Fleetwood was discontinued in 1996.
 It is built on a different platform than the smaller CTS and is engineered as a rear-wheel drive vehicle with optional all-wheel drive.
 In addition to its primary markets of North America and China, the CT6 is also offered in Europe, Korea, Japan, Israel and the Middle East.
The Ford Fusion is a four-door, five passenger mid-size sedan manufactured and marketed by Ford across three generations in gasoline and gas/electric hybrid variants.
 Introduced for model year 2006, the Fusion is manufactured at Ford's Hermosillo Stamping & Assembly plant along with its rebadged variant the Lincoln MKZ — and formerly with its now discontinued rebadged variant, the Mercury Milan, all sharing the CD3 platform.
 The Ford Fusion mainly competes against cars such as the Buick Regal, Chevrolet Malibu, Honda Accord, Hyundai Sonata, Kia Optima, Mitsubishi Lancer, Nissan Altima, Toyota Camry and Volkswagen Passat.
Transtar was the model name given to the line of trucks produced by the Studebaker Corporation of South Bend, Indiana, from 1956-1958 and 1960-1963 (although the last vehicles were sold as 1964 models).
 The name was used on most trucks in the Studebaker E-series, but not all.
 The Transtar name was first introduced for the 1956 (2E series) model year in 1/2-ton, 3/4-ton, 1-ton, 2-ton, and 2-ton heavy duty capacities.
 The three smaller models were available with factory-built pick-up bodies.
 The basic styling of these trucks dated back to the 1949 models, though they had received some styling and engineering changes in 1954 and 55.
 The Transtar name continued to be used on most of the 1957-58 3E series trucks, though a stripped-down Studebaker Scotsman model without the Transtar name was introduced in the 1958 model year.
 The 57-58 Transtars received an aggressive new fiberglass grille that attempted (largely successfully) to make Studebaker's outdated cab design look fresh and new.
 For unknown reasons, the Transtar name was dropped for the 1959 4E series Studebaker trucks and changed to Deluxe.
The Packard Model 30 was a luxury car introduced for the 1907 model year.
 It replaced the Model S.
 It featured a touring body with right hand drive and a crank starter mounted to a four-cylinder T-head engine.
 The pricey 30 was marketed just above the Model 18 (literally a 9/10 scale model of the Model 30).
 In 1911 Packard introduced the Packard Six as a 1912 model and phased out the four-cylinder Model 30s.
 The Model 30 was replaced by the Packard Twin Six as the top level car in May 1915.
The Chevrolet Corvette (C1) is the first generation of the Corvette sports car produced by Chevrolet.
 It was introduced late in the 1953 model year, and produced through 1962.
 It is commonly referred to as the "solid-axle" generation, as the independent rear suspension did not appear until the 1963 Sting Ray.
 The Corvette was rushed into production for its debut model year to capitalize on the enthusiastic public reaction to the concept vehicle, but expectations for the new model were largely unfulfilled.
 Reviews were mixed and sales fell far short of expectations through the car's early years.
 The program was nearly canceled, but Chevrolet would ultimately stay the course.
The Buick Regal is an upscale mid-sized automobile that was first introduced by Buick for the 1973 model year.
 North American production ended in 2004 and began again in 2011.
 For the 2011 model year, Buick re-introduced the Regal to the North American market, positioned as an upscale sports sedan.
 Production and sales in China have continued since 1999.

Question: A car that was introduced in model year 2006, and competes against a car that was first introduced in 1973, is manufactured where? 
Answer: Hermosillo Stamping & Assembly plant
