That's fine if you want to piss around under a car for an hour... Then have to take the used oil to a recycling centre.....
I can't be arsed, which is why I'll pay someone to do it for me.
I see your point but I like to know the job has been done properly and the oil level not over filled, as so many dealers do 
....It's too easy to tar all VW dealers with the same bad brush. I'm like Rich and I also know my skill limitations, so I go to my VW dealer, VWR, and JKM, for my servicing needs. One of my VW dealer's mechtechs is a member here and knows his stuff - I trust his work. He PDI'd my car in 2005, is a genuine GTI enthusiast, and is now the Technical Manager at VanWorx.
It's fine to DIY if you have both the skills and all the tools and it's not a sign of your manhood to have these skills and the right tool.
Apart from applying a small sticker or emptying my catch tank, I wouldn't trust me to work on my car!
