I’ve definitely noticed pricing differences even within the same brand. Dealers can set their own prices, so it’s usually down to location, competition, and the dealership’s overhead costs. It’s always worth trying to negotiate if you have a lower quote from another dealer-some might price-match or offer a discount just to get your business.
As for the warranty, check your manual, but usually, you just need to keep records of the maintenance being done at the right intervals. It doesn’t always have to be at the dealership, as long as it’s documented and done correctly. Many Hyundai owners use trusted local shops for basic services without issues.
