I am 27 years old and i have a 335xi coupe and I drove the new F10 BMW and I feel that the new BMW 5 is an amazing car to drive. Smooth, sporty, comfortable with no compromise. I careless about 'numb" steering since its still good enough. If you want a more direct one, then get the dynamic handling package. That does not mean the car is bad. I feel the 5 series is much better than my 335xi coupe in refinery and feel. The 3 series feels harsh and exhausting to drive at times over bumps, etc. Also the 3 series are sensitive to the road crowns and have heavy steering in the parking lots. I am ready for the F10 and it is downright the best 5 series in years.
And no, I do not miss the feeling of the 335xi over the F10 at all.
F10 meets and exceeds my expectations!
