Post-World War II classic cars are not precisely defined, and the term is often applied to any older vehicle.
For example, most classic Ford Falcons, Chrysler Valiants and Holdens (alongside Toranas, and Commodores) are on either of the registers.
It has been a registered Society since the mid-1950s, and a continuous member of the (NAACC) National Association of Automobile Clubs of Canada Corporation since 1971.
[citation needed] The National Association of Automobile Clubs of Canada (NAACC) recognizes stock and modified vehicles that are at least 20 years old as classics.
"[2] There are, however, two exceptions: Firstly, the NAACC is responsible for doing away with import duties at the Canadian border for all vehicles and related parts 25 years old or older.
Yet even requirements between states may vary, such as how Maryland defines historic vehicles as 20 years old or older, and they "must not have been substantially altered, remodeled or remanufactured from the manufacturer's original design".
Specifically, the CCCA term "antique car" has been confined to "the functionally traditional designs of the earlier period" (mostly pre-war).
In a large vehicle, such as a Duesenberg, Pierce-Arrow, or in a more diminutive form, the MG TC, with traditional lines, might typify the CCCA term.
[8] The CCCA is dedicated to preserving and enjoying select cars that "are distinguished by their respective fine design, high engineering standards, and superior workmanship.
[13] The Antique Automobile Club of America (AACA) recognizes "motorized vehicles 25 years old or older, built in factories and specifically designed and manufactured for transportation use on public roadways and highways.
"[18] HM Revenue and Customs define a classic car for company taxation purposes as being over 15 years old and having a value over £15,000.
In Germany, vehicles registered at least 30 years ago can apply for a special "Oldtimer" license plate with a 190€/year flat tax.
Modifications that enhance safety (seatbelts, disc brakes) and environmental friendliness (catalytic converter, LPG conversion if invisible from the outside) are universally accepted.
[22][23][24][25] Converting the car to run on a different fuel (i.e., SVO, LPG, CNG, hydrogen, ...) may decrease emission levels.
[26][27][28] Classic cars often lack what are now considered basic safety features, including seat belts, crumple zones, or rollover protection.
Vehicle handling characteristics (particularly steering and suspension) and brake performance are poorer than current standards, hence requiring greater road-awareness on the driver's part.
In certain jurisdictions of the United States, using a classic car as a daily vehicle is strongly discouraged and may even be considered illegal in some places.
[32] Some classic car owners are reluctant to retrofit seat belts for the loss of originality this modification implies.
A few of the newest classic cars (1980s and 1990s) have more advanced safety features such as airbags, anti-lock brakes, and side-impact beams.
NHTSA began their 35 mph (56 km/h) full frontal crash test program in 1979, so these results are available for many post-1979 classic cars.
