It was based on the GM A-body platform along with other cars such as the Pontiac LeMans, Pontiac GTO, Chevrolet Chevelle, Buick Century, and the Oldsmobile Cutlass Supreme. The GM A-body platform had major design revisions in 1973 that included the elimination of pillarless hardtops due to proposed federal rollover standards, but with frameless windows similar to that of a hardtop. No convertibles were produced due to those same federal rollover standards (that never were enacted).

The Grand Am had two separate 3-year runs in the ’70s: from 1973 to 1975 and again from 1978 to 1980. It was based on the GM A platform. Production of the Grand Am was canceled in 1980 when it was replaced by the Pontiac 6000. The Grand Am was reintroduced in 1985 when it replaced the Pontiac Phoenix. It was Pontiac’s best selling car and later replaced by the Pontiac G6, so named as it was intended to be the 6th generation of the Grand Am.[1] Grand Ams were built between 1973 and 1985 in Pontiac, Michigan at Pontiac’s main assembly plant and in Atlanta, Georgia at GMAD Lakewood.

Base models were well equipped, featuring power locks, windows and mirrors with keyless entry, 6 speaker CD stereo, power drivers seat, air conditioning and split folding rear seat. GTs added an 8 speaker Monsoon stereo, premium cloth seats with 6 way adjustment, remote start, ABS and traction control.
In 2006, the G6 added two new trim levels and two new bodystyles, a coupe and a retractable hard top convertible. The new trims we’re a new base four-cylinder trim (sometimes referred to as “SE”), and the high performance GTP.

The car is built off the GM Epsilon platform which it shares with the Chevrolet Malibu and Saab 9-3 along with other General Motors vehicles. Styling was redone in a more conservative fashion, and the ribbed cladding and rear spoiler that were prevalent on the Grand Am was replaced by standard sheet metal.[2] New features included a remote starting system as well as a panoramic sunroof option.

By 1964 Nissan realized that Yamaha’s DOHC 2.0-liter engine was not meeting Nissan’s expectations and the project was scrapped. Yamaha later finished a prototype and took their design to Toyota, resulting in the Toyota 2000GT. Yutaka Katayama, the president of Nissan USA at the time, realized the importance of an affordable sports car. Nissan had already produced the successful series of Fairlady roadsters that competed mainly with English and Italian roadsters, and product planners envisioned a new line of GT cars that would be stylish, innovative, fast, and relatively inexpensive through the use of interchangeable parts with other Nissan vehicles. Prototype work began in 1966 with a clay mockup.

The original Z was sold in October 1969 in Japan as the Nissan Fairlady Z and was exported as the Datsun 240Z. Since 2009 Nissan has manufactured the newest Z, the 370Z. Enthusiasts praise the cars for their looks, reliability, performance, and affordability. Nissan Z cars currently hold the record for best selling sports car series of all time with around 1,685,000 in five generations. Every Z car has been sold in Japan as the Fairlady Z and elsewhere under the names 240Z, 260Z, 280Z, 280ZX, 300ZX, 350Z and 370Z.

A Formula option was available on coupe and hatchback. It includes the handling package, a chrome valve cover, three-piece spoiler, T/A steering wheel, and special body decals.

In the 1978 model year the discontinued Vega/Astre hatchback and wagon body styles were added to the Sunbird line. They continued to use the same front fascia as the Astre with Sunbird badging. The 2.3 L engine was simultaneously discontinued.For the 1979 model year, the Chevrolet’s 5.0 L (305 cid) V8 engine was made optional in the notchback and hatchback, while the Astre based hatchback was discontinued. The Sunbird Safari wagon continued for its final year with a revised verticle styled grill.

1980 was the final production year of the H-bodied Sunbird. By this time the wagon body style and the optional V8 engine were discontinued. The year featured an unusually long production run in order to provide sufficient inventory to carry dealers into the 1981 model year, in anticipation of the Sunbird’s replacement.

The Pontiac Sunbird is a subcompact, four-passenger automobile introduced in September 1975, and produced for the 1976 through 1980 model years. The first-generation Sunbird is based on the Chevrolet Vega, shares Vega’s wheelbase and width,and is part of the H-body platform. Its intended competitors were other small sporty two-door vehicles of the time, such as the Toyota Celica, Ford Capri, and the Ford Mustang II

The standard engine was the Vega aluminum-block 140 CID inline-4. Equipped with a single barrel carburetor, it generates a peak power output of 78 horsepower (58 kW) at 4200 rpm. the standard transmission was a 4-speed manual, with a 5-speed manual and 3-speed automatic transmission options. This engine was also available with a 2-barrel carburetor that increased peak power to 87 horsepower (65 kW) at 4400 rpm, as well as Buick’s 3.8 L (231 cid) V6 engine rated at 110 horsepower (82 kW) at 4000 rpm.

It was designated officially at Pontiac as a “regular performance” model[3] created to fill the affordable sports market niche between the base Catalina, upon which it was built, and the brand new GTO. The 2+2 was intended by Pontiac to be to the Catalina platform what the GTO was to the Lemans. Standard on the 2+2 beginning with the 1965 models was a high-compression 421 V8 powered through a 3-speed manual transmission, with 3-speed automatic and 4-speed as optional equipment. Consumers also had the option of ordering an array of induction setups to feed it, like a single 4bbl carburetor or a 3×2 configuration, called Tri-Power. The suspension was stiffened for improved handling with heavy duty springs and sway bars. When it was discontinued by 1968, all options were still available to consumers, and a purchaser could still effectively build themselves a 2+2, just not with the badges.

Pontiac Motor Division and debuted in 1964 as an interior trim option with special door panels, buckets seats and center console on the full size Catalina. Beginning in 1965, the name Catalina was no longer found on the car any where. The cars were given the famous 421 cubic inch power plant, dual exhaust, heavy duty front springs as well as its own outer body trim appointments. It officially became its own series according to the numbers [1] in 1966, on the same platform, but reverted again to an option in 1967[2] and was discontinued the same year due to poor sales. Make no mistake, from ‘65 through ‘67 the 2+2 was distinctive. It continued as a series in Canada until 1970. The 2+2 was produced in low numbers and are fairly rare cars today as many were lost to the drag strip as well as the crusher. Though they have managed over the years to remain a well kept secret, they are beginning to come in to their own as people are realizing that they are a highly collectible automobiles. Due to their rarity, there is much misinformation about these cars in print.
