资料题：When checking the outside of the car, you should look for（　）。

The first step in wise car care and service is to buy a car that is in perfect condition.Look the car over carefully to make sure that it doesn't have any built-in flaws or service headaches.Be sure you know how to operate your car.Sit in the driver's seat and have the salesman explain how to start the car.He will show you the gauges and the warming lights.He will also point out the knobs and controls.Make sure you lean the location of all the controls.Read the warranty well and note the services that are free.Find those that you must pay for.Be aware thatthe new car warranty will not pay for normal wear or abuse.You must pay these costs yourself.Check the outside of the car.Look for dents or scratches in the paint." Check inside the car too.Look at the seats.See if there are tears, scuffs, or crooked seams.Check the door panels and headlining for these same flaws.Do the rug and floor mats ft well? Open and close the car doors two or three times.Do the doors ft the frames? Do they close completely? Roll the windows up and down.Do they work smoothly and close all the way? Have the salesman try all the lights and tum signals while you stand outside the car to make sure they work.Look in the trunk for the spare tire.Find the tine jack and lug wrench; make sure they are there.Ask the salesman to show you how the jack works.Look under the hood at the engine.Is it new and clean? Ask how to check the oil level and other fluids.Start the engine and listen for any noise.The car should run smoothly after it has warmed up.If the car has an automatic transmission, step on the brake and shift to“drive.”The engine should run without stalling.All these simple things should be checked before you leave the dealer's lot.Next, test the car on the road.It should speed up without jerking, and the brakes should work evenly and quickly.The steering should be smooth and sure.Try the horn and the windshield wipers and washer.If the car fails to operate on any of these points, do not take it.Insist that the faults be fixed before you accept it.
