If you've already set a number of types or models and brands, analyzes the advantages and disadvantage. You can get information from friends who ever use the car. You can also from site about automobile and automobile clubs that exist. Find information as much as possible from each brand, including the resale value, performance, service improvement and cost or availability of components. From there you can determine where the car is truly appropriate. If you have decided which car will be purchased, this is the next guidance:

• How big your desire, your head should remain cold. Leave the seller if the price offered too high, even if your dream car is waiting. Your negotiation ability will increase with time leased.

Dig information, including as much detail as possible if ever sinking, accident, etc. engine down. Before deciding to buy it, ask for the mechanical engineers to investigate.
• Test drive is essential. You should get the opportunity to test drive as far as possible with the various of road. You can also try on the regions where the car will be used.
• Open the engine cover and see if there is a pipeline leak, a worn belt, oil spreading. Sit on driver seat, and check if all the indicators work well, including lights indicator. Check also if any signs of damage due to water (see tip disaster prevent continuation). Check the safety system, from the seat belt, head restrain, roof structure, child seat anchors. Similarly, the distance of approach and the main power of light scattered. This can be done during the test drive. Try to drive the car at the speed of 60 then 80 km/hour, and feel whether the replacement teeth can be soft, the rudder is straight, when break remain stable, and when turn curve is also smooth.
• Be careful with forgery speedometer. This is often done by prankish sellers who want to increase the value of the car price. So do not deceived by the numbers listed on the speedometer.
• Check the car license, this license can be check by send sms to certain number than will get reply about the car status, every country have different phone number for this purpose. For this purpose you should check directly to the department in charge on your country.

Car Steering System

An automobile steering system allows the driver to control the vehicle’s direction. Rotation of the steering wheel is translated, through gearing and a network of rods and joints (the steering linkage), into right or left movement of the car’s front wheels.

There are two basic types of steering systems, rack and pinion, and worm and roller (or worm and key). The rack and pinion is the simples, and the one most commonly used in modern cars. In rack and pinion linkage, the steering shaft, connected at one end to the steering wheel, has a pinion gear at its opposite end. The gear meshes with threads in a steering rack, which is mounted across the car and is connected by the rods to the front wheels. The steering wheel turns the steering shaft, the pinion gear on the shaft’s end moves the steering rack to the right or left and thus moves the wheels. Rack and pinion systems use how few moving parts but perform precisely and efficiently.

In worm and roller systems the steering shaft ends in a gearbox, which is connected to the steering linkage by a special rod called a Pitman arm. On the left side of the car, an idler arm is mounted parallel to the right mounted Pitman arm. The arms are connected by a relay rod. Inserted into the relay rod are tie rods connecting it to the two front wheels, and short tire-steering arms that are joined to the tire rods by ball joints. Inside the gearbox the worm – a spiral threaded gear on the end of the steering shaft meshes at right angles with a roller, or a key. (A roller is a threaded gear; a key is a device with a single tooth that engages the threads of the worm gear.) As the steering wheel is turned, the roller or key moves right or left along the worm gear, swiveling the Pitman arm.

The recirculation ball steering gear resembles the worm and roller mechanism, except that the gears ride on a number of ball bearings, which act as lubricants, reducing gear friction.

Many modern vehicles have power assisted steering, which uses hydraulic pressure to reduce the effort needed to steer. In the most common system, a power steering pump, connected by a belt to the engine, sends high pressure fluid to the steering gearbox, where it aids in moving the gear.

Innoactive 4 wheel steering (4WS) is now available in the modes, either all 4 wheels turn in the same direction, or front and rear wheels turn in opposite directions. Both systems are said to produce the same effects; parking is far easier, and high speed maneuvers are safer because fishtailing is reduced. In either mode, 4WS is still relatively untired, but it may prove eventually to be the steering system of the future.
