Just had the oil changed and a couple warranty updates performed at Porsche in Westwood ,Ma. 360.00 , and a nice full printed out inspection report . I know I can service for less ? I was interested to see if any oil leaking was present and wanted to document it for warranty purposes . My 2017 S at 35,500 mi is very dry and clean at the moment , so to me its a fair value . Having people who only service these vehicles has significant value . That being said I will do my plugs myself . I will also do any brake and tire work . I will continue to let the dealer change oil as a 10,000 mi service , this way I will be made aware of any pending issues .
