I have been around and owned Korean cars for 15 years and counting

so this is a true narration and not dramatized

- spare parts and repairs for Korean cars ARE AS EXPENSIVE IS MERC AND BMW

ive been waiting for 15 years for such a good advice

any recommendations to change workshop to?

Either you are still in 200x or you had a really old Merc and BMW. Mercedes E300 service only already close to 1K even when you are servicing outside. If goto SC, already 1K++.

As for Kcars, I drove a company provided Sonata. I had enquire about bumper, headlights as some bastards bang me while being park outside. Not much difference from say Camry. Things that are costly for Kcars are things that you dont often change like windscreen, sunroof etc. Parts that are normally wear and tear like brakes, engine oil, filters, absorbers, lower arm are not much different from T and H. Dont come around with your Vios part pricing and compare with Sonata.
