Inspect a Used car Before buying ~ Part 1

I have a colleague who sold out his Toyota Corolla SE Limited on March. Then he purchased a used Toyota Altis in May. After he drove Altis for two months, the problem " appeared". Therefore he sent the car to mechanic( few mechanic shops) to examine and repaire,but the problems still dint solve. Finally he sold out the Altis, and now purchased Toyota Camry. He learned a leasson from buying Altis, as he dint really test drive and examine it before buying.

Here, i have few opinions to share with you about what / how to inspect before buying a USED car...

1. Look at the car's exterior such as bumpers, wheels and unseen area as normally the exterior often distract from larger problems such as underlying rust.

2.Look for inconsistencies for both sides of the cars as they may be clues to previous wrecks.

3. Besides,we need to check the interior for tears in upholstery, ensure the air conditioning, sunroof, power steering, air bags are in good functionality.
