Yes it's not too far, probably 30-45 mins depending on traffic.
Michael Stead Porsche dealer is also in walnut creek if you are looking for another dealer.
I'd actually say a better or as good Indi mechanic that will be closer is "kahlers" in Dublin. They are 10 mins from Livermore area probably and are a reputable Indi shop. Local PCA has ads and works with them sometimes. Livermore dealer would also be good I would imagine too but sounds like you need to go elsewhere for info...
