I've been recommending this shop since Day One:
Fix N Go | the Porsche Specialist
The owner Danny is the only one I'd let near my Boxster for major service or repair. He's extremely knowledgeable, personable, and reasonably priced. Plus, he's got one helluva impressive CV:
Danny Kaheh | LinkedIn
Don't be misled by the name of his shop. Danny knows his stuff, and will work with you in regards to any service.
Just sayin'............
