I want the fastest and nicest car of these...should I go lexus, audi, or infiniti?

I'm not looking to spend over $60,000 and I want a new car that has all the bells and whistles...don't know much about cars, what features make them go fast and what I should specifically look into, but I know those 3 brands are in my price range, I was thinking bmw but then I learned they aren't very reliable...so advice please?
