Suggestions for which Hyundai service dealership to go with ?

Vanakam makale, I've got a hyundai car recently and was looking at reviews for Hyundai car service, the review section on Google seems to have mixed reviews ( or may be even fake ones ), since I've seen so many Hyundai's around in our Kovai - do let me know which dealership is great / lesser of the evil. Also let me know what I should watch out for ?
