For sure RS4B7 sound better. And now for sure is cheaper, but its propably not too good at reability and parts prices kill it.

One of the best Audis ever.

RS4 without a doubt. Better engine even if does not hold the power, far better 4WD system, better to drive, RS4 is simply a class above. A45 great car tho.

..Id prolly take the RS4, new and old, but I really wouldn't care which one. I always thought the Interior of the A45 Never went with the car, And that it should have been a coupe rather then a saloon, maybe less space, but also less weight, and better for the looks, same with the RS3. Id also be willing to bet the A45 is making a good deal more then 360Bhp...seems to be a trend nowadays..

I prefer A 45 Amg more than new RS4 B8. The old B7 looks realy like its generation behind, even it was a very good all-around type of car.

They are also similar fast, but i prefer lighter machines so i go with Merc. Event its V8 vs 4 cyliner.
