Aftermarket modifications refer to changes or enhancements made to a vehicle after its initial sale. These modifications can include upgrades to performance, aesthetics, or functionality, such as installing a new exhaust system, changing the wheels, or adding a custom paint job. Many car enthusiasts pursue these modifications to personalize their vehicles or improve performance. These modifications can vary widely in complexity and cost. Some common aftermarket parts include suspension kits, performance chips, and body kits. While aftermarket modifications can enhance a vehicle's appeal and performance, they may also affect warranty coverage and insurance rates.
