Everyone does make mistakes, no doubt. I do think we expect nothing but the best from a dealer since they are reps of the motor company and because they charge a premium. Most of us know the deal where not everyone is certified, a lack of allegiance (which is everywhere) and money is tight for everyone including the dealer. When the errors outnumber the positives though, it's a huge problem. This certainly isn't limited to auto dealers or even the field. I think the medical field is surpassing the trend of bad mechanics and that will no doubt get worse. I applaud anyone that runs a dealer, shop and even the shade tree mechanic. The biggest problem are people, not all of course but it seems like the chuckleheads outnumber the normal ones. Back to vehicles, no matter what you do, preventative maintenance is the most important thing to stay on top of getting the most out of your machine.
