Indeed（固然）， three out of four sales today are used cars， and theyre not cheap junkers （废物）eitherthe average price now is $ 5500， about half what a new car costs. Make the wrong selection and a major investment （投资）can be lost the moment you drive off the lot.There is far less chance of this happening to you if you know： when to buy， where to buy， how to examine （认真检查） the car， how to conduct （进展） your own road test， and how to bargain over （讲价）the price.When to buyShop during the day. Lighting makes cars gleam （V 闪光）like jewels （宝石）at night. In daylight they look dull （黯淡的）， but realistic.Dont shop in the rain. It can mask（掩盖） liquids （液体） that might be leaking （泄漏）。 If possible， shop in the winter when supplies are high and demand （需求）is low.Where to buyShop the suburbs. In more affluent （富有的）neighbourhoods cars are more likely to have been well cared for.A private owner normally sells a car for less than a dealer（商人） does， but almost always “as is，” with no guarantee（质量保证）。 Thats an acceptable risk if what youre looking for is a cheap second car to “drive to the station. ”Even though a used-car dealer generally charges more， you can often get some type of limited guarantee. This is often a 50-50 plan， in which you each pay half on repairs for a period （一段时间）that may range from 30 days to a year. Ask the dealer about the availability of an optional（可选择的） service policy.Used-car dealers often claim （声称）to have gone over （认真查看）the car， and many have. But remember that small dealers often buy cars that are auctioned （拍卖 ） because nobody else wants them.Some experts feel that a new-car dealer is the best place to buy a secondhand car， especially if youre laying out a large sum （一笔金钱） for a late model. Some of these dealers offer extensive （宽阔的）guarantees， such as one on the “drive train，” which covers any problems with engine （发动机）， transmission（变速器） ， drive shaft and differential （差速器 ）。 Expect to pay for this， as well as for the markup （标高的价格）。 But if you shop soon after the new models have arrived， when a dealer has a lot of trade-ins tying up his profits， he might deal. The visual examination （视觉上的检查）Youve found your dream car， and can hardly wait to get in and roar away. Wait.First， look for any flaws （瑕疵）or ripples（划痕） in the body that might indicate a past accident （示意曾经出过事故）。 To see if a car has been repainted（重新漆过）， look under the rubber seals around the door or under the chrome trim. Repainting may mask deep flaws （重新上漆可能隐蔽深层的瑕疵）。Check the odometer （计程器） for total mileage （英里数）， and then compare that figure （数字）with any stickers still attached to door posts. Its illegal to change odometer readings， but it happens. If there are no stickers， be a little suspicious. Check pedals and controls： wear on these parts should agree with the mileage. If they are brand new， be suspicious. If they are worn out， beware.Check that the doors， hood and trunk all open smoothly and close with solid sound. Sight along the sides of the car from 30 feet away to be sure that the rear and front wheels line up.Look under the car for fluid leaks. Except for condensation from a working air conditioner on a hot day， no car should ever drip anything， any time.Now sit in the drivers seat and try the controls. The car should fit youit should be comfortable. Check seat adjustment， door locks， window-raising mechanisms， horn， lights， directional signals， radioall accessories.Start the engine. It should turn over quickly and then settle down to a rather fast idle. Give the engine a moment or two before you press the accelerator a bit. Watch for smoke from the rear. Blue smoke might mean a complete engine overhaul （大修） ， black a maladjusted carburettor （化油器）。 2White smoke can be.ignored if the engine is cold， but once it is warmed up， white smoke can mean a leaking head gasket （垫圈） ： expensive. Reject this car.After the engine has warmed， shut it off， and then go wipe your finger inside the tailpipe （making sure its not too hot）。 The residue should be whitish-gay. If you get a black， oily mark， refuse the carits probably an oil burner.Restart the engine and check the oil in an automatic transmission. It should be clean and clear， with no bu
