i personally believe it boils down to Expectationssss
i have never assuemed and expect i can get 100% cheapest Deal when ever i needed somethings
MY best Deal defined as Trust (base on product Quality ,Workmanship , Responsibilty when come to Aftersales service)
Convenient time to me,
Professional and Friendly, Knowledgement Person.
(they Know what are They Promoting or Selling)
Price isnt my !st consideration ,ONly spend within my affortability
I always Enjoy almost all my Purchase or Services by most of my Service providers (Automotive) except for some issue with mY new car with the BIg CAr AA.
My personal experient with Relatively Smaller Establishment is always Best .
Sorry to here about some Bad encountered with some shop ,
Prices and year made now aday became very challenging for Every Sellers and Buyers.
Life is Short , Enjoy your CAr(not cheap to me) with all the Necessary Shopping.
If you Like 1 specialised WS why not just stick with him and Tell him what you are looking, I am 99.99 % sure he or she will do their best to Source for you ,So long you are their Reasonable Supporter.
Rather than you know your Own Homework and sometime you will end up bad Encounter.
