The Origin of Certified Pre-Owned Vehicles

October 1, 2014  

low mileage cars in Weldon SpringMost reputable dealers who sell used cars, like 5 Star Auto Plaza, strive to meet the standards of car manufacturers for overall vehicle quality when purchasing any inventory. This results in CPO or certified pre-owned vehicles. A buyer can then be assured that when purchasing low mileage cars in Weldon Spring from 5 Star Auto Plaza, that a purchase will hold up to usual wear and tear on the road and last for many miles to come.

One long ago pre-curser to CPO was the Hudson Approved Reconditioning Procedure or HARP that debuted in the 1950s by the Hudson Motor Company in Detroit, Michigan. Their 13-point check system is almost laughable in today’s used car world. Such hands-on treatment was virtually unheard-of but is a model on which our current specifications exist.

Consider this HARP protocol:

  1. Clean engine and chassis.
  2. Clean interior and trunk.
  3. Tune and adjust motor.
  4. Lubricate.
  5. Road test.
  6. Write complete repair order.
  7. Perform minor mechanical adjustments and repairs. Major overhaul if necessary.
  8. Check electrical system and repair if necessary.
  9. Check tires and re-groove or replace if necessary.
  10. Wash car.
  11. Repair body and paint if necessary.
  12. Polish.
  13. Interior appearance recondition.

5 Star Auto Plaza makes sure to meticulously inspect each vehicle that we take in as inventory for our lot. Our in-house service department combs all vehicles both inside and out to ensure quality standards for reliability and overall vehicle care are met and often exceeded.
