I was just browsing

And now I think I am comparing apples with oranges.
Though Accord is bigger, but A4 is luxurious with millions of advanced features like
adaptive lights (which move when you turn stearing)
Seperate Air Conditioning for Rear seats,
Automatic Climate Control,
Night and Rain sensors which turn on lights when night hits and automatically turns on vipers when it starts to rain.
Side Assit, which tells you with blinking light on the side mirrors if there is a car on the blind spot. AWESOME feature!
Adaptive Cruise Control, keeps a safe distance from the next car and accelerates itself and apply brakes itself.
Band and Olufsen Sound system, with 14 speakers including subwoofers.
Big wheels,
Interior Mirrors with Automatic Antiglare action, when someone behind you turns on High beam, the mirrors are automatically dimmed.
Electrical rear blind
Rear Camera
Advanced Key, actually its very advanced, You actually never have to touch your key. Just keep it in your pocket and the door will open automatically when you open the door.
Push Start button to start the Engine
Sport bucket Seats
Heated front and rear seats.
Traction Control
Drive Select, choice between, Comfort and Sport.
Hill Hold Assist. Car don't go back when you release accelerator on high road
Lane Assist. The stearing Wheel vibrate when you leave the lane without giving indicator. very helpful on motorway, will save you if you go to sleep while driving 
Rear Side Airbags
and there are many more.
All of these features are not offered in Accord.
Looks like I was a fool comparing these two. damn
