Certified used cars have become overwhelmingly popular these days. With everything that the dealer’s say about their “certified used cars,” you would believe that they are a safe bet. Don’t count on it. In a recent story, one lady bought a GM certified pre-owned car that turned out to be two cars welded together! And GM has said absolutely nothing about it. The average extra price paid for a “certified used car” as opposed to one that isn’t certified is $2,000. When you are paying “certified” price but aren’t really getting a “certified” product, it is just wrong. So avoid some of the pains you can have and pay an ASE certified mechanic to take a look before you buy. It might cost a little up front, but save you a lot in the long run.
