If you plan to keep it for a long time and don’t want to worry about cost of maintenance after the warranty is over, I suggest sticking w/ the Japanese brands. They are usually very reliable and relatively inexpensive to maintain, even by the dealer. If you want to go cheap, you can always bring your Acura to Honda’s dealer, Infiniti to Nissan’s dealer, and Lexus to Toyota dealer and they’ll maintain it for you.
