good workshop are rare
and most of it are just small shop/small business
those huge workshop are usually unreliable(my experience)

i mean outside workshop
exclude those official SC
those official SC also got problem one, say change this and that..end up did not change anything
for outside workshop, they simply just change whatever is needed...and they won't perform any further checks...thn straight give back to u
those big workshop charge u very high price for something like alignment and its not even straight when handed back to u

so a reliable workshop is rare
