Interior

While upgrading the exterior is nice, you spend most of your time inside your vehicle, so modifying the interior is just as important. Adding leather seats, a great sound system, and a sunroof can help make the driving experience much more enjoyable. Cruise control and satellite radio are perfect for drivers who spend multiple hours on the road, while a GPS system ensures you always know where you are going. In the age of the smart phone, hands-free calling has improved safety, while upgrading your airbags helps prevent serious injury in the case of an accident.
