‘73% of car owners resort to aftermarket mods’
Friday, July 13th, 2007
Consumer Reports, a monthly US magazine published by information organization Consumers Union, said that 73 percent of adults whose household owns a vehicle had personalized their principal vehicle via some aftermarket mods, or intend to do so.
The survey reveals that car personalization cuts across all major demographic segments, whether the car was purchased new or used. It adds that average spending on aftermarket mods of automotive enthusiasts stands at $711 per car, or an estimated $13.5 billion annually for the total population of car owners ages 18 to 64.
The survey defines personalization as any aftermarket modification from the new or used vehicle’s original condition, made or planned after sale by the owner. It reports that the most common aftermarket upgrade is floor mats but the enhancements range all the way to the performance end of the vehicle.
To learn what aftermarket products Americans buy for their cars, and why, the national research center of Consumer Reports conducted a random, nationwide telephone survey from Oct. 12 to 15 last year, with a survey population of 855 adults ages 18 and older whose household owns at least one vehicle.
The study finds out that both sexes are engaged in car personalizing, with 77 percent of men and 70 percent of women participating in the aftermarket mods tradition. It adds that, despite the effects of car-related movies, TV shows, and video games on the youth, age groups defy stereotypes and are likely to follow their own style. Expectedly, the 18- to 34-year-olds are the most active group—78 percent enhance their ride—while 35- to 54-year-olds follow at 74 percent, and the 55-and-over crowd is involved at 68 percent.
Most aftermarket modifications were done to the interior, with 61 percent of respondents who own a car making the cabin more comfortable and conducive to their mobile lifestyle. Aftermarket floor mats lead the changes at 49 percent. An easy install item, floor mats are not standard on all cars and may be less expensive when bought in the aftermarket segment of the automotive industry.
Plus, custom-made aftermarket floor mats are said to add character to the car, while deep, rubber mats can protect against mud and snow. Other low-cost, low-effort aftermarket upgrades include steering wheel cover (18 percent), seat covers (17 percent), shift knob (5 percent), and dash appliqués (4 percent).
The study likewise reveals that half the car owners surveyed plan to change, or have changed, in-car electronics, with stereo systems heading the list at 28 percent, despite the trend in factory-supplied units sounding better and being increasingly difficult to replace. At 22 percent, aftermarket car alarms and speakers are also common.
Satellite radio units are logged in at 13 percent—a relatively strong return considering that many new car models offer Sirius or XM systems as standard or optional features. Hands-free cellphone setups also came in at 13 percent. Consumers also looked to high-tech luxuries, such as video systems (10 percent) and navigation systems (9 percent).
A third of consumers pursued the exterior modifications in some way, led by aftermarket performance headlights or fog lights (11 percent). Three-quarters of pickup truck owners surveyed have installed, or plan to install, an aftermarket bedliner. This is a significant figure considering some models, such as the Chevrolet Avalanche and Honda Ridgeline, come stockfitted with bedliners.
Other aftermarket modifications are less common and split between cosmetic and functional. At 7 percent, aftermarket spoilers were next in the ranking order, trailed by roof/bike racks (6 percent), brush guards (6 percent), and pin stripes or other body art (5 percent).
On the performance end of the vehicle, the most common powertrain upgrades focused on improved engine breathing, with the aftermarket performance air filter or intake leading at 17 percent, and aftermarket performance exhaust or muffler at 11 percent.
One in 20 drivers, or 5 percent, have made or intend to make a significant performance commitment by adding an aftermarket turbocharger or supercharger, devices that force air into the engine to generate more horsepower. With similar popularity, enthusiasts installed aftermarket performance computer chips (6 percent) and new pulleys (4 percent).
Chassis modifications are made by, or planned by, one-third of personalizers, led by one of the most-effective component upgrades: performance tires (17 percent). Aftermarket wheels followed at 12 percent.
