Changing of parts thats nothing wrong with

<p><span style="color: #555555; background-color: #ffffff;"> nothing wrong with my discs and that there is still 20 % life remaining on my brake pads . How is it possible that i have to change discs after only 24000km ?? Other than that the engine was a mess and that *****s where missing on some of the engine covers ! Is that how you work on all your cars , try and make money of anything you can that is still fine ? For a car that costed me almost half a million to buy , i must say this is very disappointing. GM has lost another client due to lack of quality workmanship. Car has been sold as this seems to be the going trend where they want to make money on anything they can , good luck to the new owner </span></p>
