For the car enthusiast in your life, or perhaps for the friend who lives in his car more than at home, the holiday season provides ample opportunity to bestow an appropriate gift on friends and loved ones. One advantage of shopping for helpful gadgets is that you don’t necessarily have to break the bank. For under a hundred dollars, you can give somebody special a useful item to make their driving experience more practical and pleasurable.What is the best car gadget to give this Christmas? It all depends on the beneficiary’s personality.The Long-Distance Traveler: Maybe he drives in and out of state for work, visiting satellite offices or working to adjust insurance claims or as a salesman. His job may take him to some far out places, beyond the security of the interstates, and he knows it’s easy to get lost. The purchase of a quality GPS system can keep him constantly on the right path, for business or leisure travel.The Informed Commuter: Maybe she drives an hour or longer to work and gets most of her news from the radio. If she’s not satisifed with local stations and has talked about subscribing to satellite, you can give her more motivation with such a system. Averaging around $150, a satellite system gives your driver access to a multitude of stations – every genre of music, and news and talk radio. Subscription rates may vary.The Off-Road Adventurer: Your friend drives to get away from it all, and usually ends up on rough terrain. A detailed auto emergency kit with jumper cables, flares, and other helpful tools is a must.The Parent: Carting kids around to school and on long vacations can take its toll. A portable DVD player can relieve some tension for Mom and Dad as the kids enjoy a favorite movie in the back seat. Most DVD players come with cigarette light adapters and are priced anywhere from $75-150.It’s easy to match the personality of a driver to the perfect holiday gift. From gadgets that help with direction to those that ease the commute, you can give practically without going broke.
