Oil change at trusted mechanic vs. Dealership

[woody3260]

I'm a brand new Porsche Boxster 986 owner (2001 Base, 76k miles). Apologies if this question has been asked a million times before.

I want to get the car's oil changed for a fresh start. Local Porsche dealership quoted me $340 for a straight-up oil change. My normal mechanic, whom I explicitly trust, has saved me tons of money over the years, and has worked on every car I have owned, said he was more than comfortable doing the job. Even said his shop did an oil change on a Porsche a week ago. His price was $75. I've watch the DIY videos on how to do it - it's not difficult (but something I am not going to do myself). Question is...do you think it is OK to use a third-party mechanic for an oil change in a Porsche? Thanks for honest feedback.
