What to look for in when buying a used car wholesale ?

Check the car shocks, go to the exsaust pipe in the back and swipe ur finger in there. If the color is black then theres engine problems. Check ur milege. Test ur ac nd heat. Listen for any noise when starting up and driving and stalling. A car should run smoothly without any noise. Drive the car rough. Make harsh turns Nd switch into reverse and drive quick so u can see if theres transmission problems. Also check ur oil colors and brake pads. If everything if goood ur all set for buying :)
