For a passive buyer, these things are but ordinary terms used in the automotive market but for someone meticulous and who wants the best for his auto, these things matter considerably. Deciding which among these to purchase is just like deciding what car to buy.

O.E.M. stands for Original Equipment Manufactured. This means that OEM Ford parts are manufactured by Ford itself, Chevrolet parts are manufactured by Chevrolet, Toyota parts by Toyota, BMW parts by BMW and so on. The terms O.E.S. and OE are also used; these mean Original Equipment Supplied and Original Equipment, respectively. While in many cases, OEM and OES mean the same, OE is more general referring to any part that came as original equipment on the car. Some of OE car parts and components are not actually made by the car manufacturer but are purchased and assembled by the automakers to create a vehicle.

Those referred to as ìaftermarket auto partsî are not made by the original car manufacturer; furthermore, they are bought and added to the vehicle only at the dealership or after the vehicle left the dealership. In terms of design and function, aftermarket products are almost the same as the stock auto parts since they are primarily used to replace a damaged original part so that the vehicle can continue to run. If you need replacement parts for your car, however, you can either buy O.E.M. or aftermarket auto parts. There are numerous sources of aftermarket auto parts. Stores like Auto Parts Discount give you a great variety of parts for almost all makes and models.

Some cars, especially the base models are not completely equipped so users just add aftermarket parts later on. For example if you have purchased an old Toyota Corolla, you can add aftermarket Toyota fog lights, Toyota spoiler, Toyota turn signal light or Toyota mirrors. Aftermarket products can also help you give your car a fresh new look. Even if your original parts are not yet damaged or worn out, you can replace them with or add specially designed aftermarket auto parts like Honda taillights, Ford center cap, Chevrolet chrome bumper, and Mercedes Benz Front Cover Towing Eye found at Auto Parts Discount.

Enthusiasts, on the other hand would opt for custom parts and specialty equipments. Compared to a universal fit auto part, which can be installed to any vehicle make, year and model, custom aftermarket products are designed to fit only a particular application. Examples of custom parts are your Ford hood, Ford fender and Ford doors. Specialty equipments on the other hand, are intended to make the vehicle more stylish, comfortable, convenient and more up-to-date.

Most auto users prefer aftermarket products because they are less expensive than OEM replacements. While it is true that there may be some aftermarket auto parts that do not meet high standards of original equipments, it is not right to say that aftermarket products are generally inferior in terms of quality and style. Replacement parts sold at Auto Parts Discount, for example are made by car parts manufacturers that are mandated by high international standards.

Which is better, OEM or aftermarket replacement part? It depends on the product. Some OEM parts are not durable enough while the aftermarket parts you use to replace them could last for many years. If you want to give your car a different look and also, if you want to save, aftermarket products are worth a try. However, make sure to get these replacement parts from trusted sources.

Whether buying used or new cars, both options have advantages and disadvantages that the car buyer alone would be the best person to be knowledgeable about as he or she would know what would work well as according to his/her needs, wants, preference, budget and whim.

The following are basic factors to consider in buying a used or a new car:

The price.

Those on a stringent budget would find used cars a good deal. Though there are a handful of new cars that sell for less than ten thousand dollars, the ones that cost less usually have only a few amenities, with some having none of the following: air-conditioning, stereo. Sometimes the cars come with only two doors or one of the power windows is broken, if there are power windows at all. On the other hand, the availability of three to four-year old used cars loaded with more than the bare-boned features of a basic used car ñ such as a CD player, air conditioning, airbags ñ gives the used car buyer a great deal.

But still, the pricey new cars are costly because of the updated safety features they carry: de-powered airbags as well as ìsmartî front and side protection airbags. New vehicles also carry whimsical features such as: beverage holders that keep drinks cool or hot.

The choice depends on you, your priorities and your purchasing power.

The warranty.

New vehicles usually are under warranty for a minimum of three years to a maximum of ten. Hyundai and Kia provide ten year warranty for their vehicles. DaimlerChrysler offers a seven year warranty for their Chrysler, Dodge and Jeep models. So does Isuzu.

Some eligible late-model used cars could complete their original warranty and could just as well be extended if they are protected by the vehicle certification program. If not, used car owners could shell out a few hundred to be able to extend their service warranty or contract.

The mileage.

Newly-bought used cars come with mileage already spent. New vehicles basically do not need maintenance for the first thousands of miles, and if they do, car manufacturers cover the oil change and their tune-up as well as other fundamental maintenance services.

Specially made cars

Used car buyers usually have to content themselves with as-is vehicles whose color may not be that perfect shade of red, green or blue. Buyers of new cars however, have the option of a varied range of colors or car features that used cars have not. Car dealers usually cater to the tastes and impulse of a car buyer and usually would even satisfy a customer by specially-ordering a vehicle.
