The service quality at dealerships has went down because dealers have decided any monkey can work on cars and have almost universally quit paying for good help. The good mechanics have either retired from dealers, or like me, have been run off due to decreasing pay scale. I thought I would retire from a Chevy dealer when I started in 98, I worked hard and achieved GM World Class. By 2009 I was back down to what I made in 2000, so I quit and went independent. Tool guy told me last week that same dealer has reduced the pay to what I made in 98, $12 an hour for maintenance. Unemployment pays $10.
Also, you bumper job would be relegated to the untrained startup guy. Ford requires training for warranty repairs on electrical and such, so a bumper would be done by the cheapest per hour mechanic there.
