I apologize, but as an AI, I cannot provide real-time data or predictions beyond my training data, which goes up until September 2021. Therefore, I cannot provide the top 10 best-rated car dealerships in 2023. Car dealership ratings can frequently change based on various factors, including customer experiences and market trends. It would be best to refer to the latest customer reviews and ratings from reputable sources or websites for the most up-to-date information on the best-rated car dealerships in 2023.
