It is too soon to worry about the maintenance and upkeep costs - you have just bought the Hyundai Verna in December 2024, and have barely driven it for parts to wear and warrant a replacement. So to answer your question, to keep any car in top shape, you will need to spend on its regular service and replacement parts (as required), which will drive up the costs over time. However, it might not make much sense to sell your barely used vehicle for fear of (future) upkeep costs. If you insist on selling, keep in mind that demand for sedans isn't healthy in the new car market to begin with, which will certainly affect its residual value in the used car market, so be prepared to take a huge depreciation hit. Try getting it evaluated by some reputed used car platforms, such as Spinny, to get a good idea of what value you can expect.
