Similar to me, I only had my 3.0i for a short time but loved it. Only had the roof down on a few occasions but simply was not practical for me in the end.
I did the same as you are planning to do but I went for the E46 M3
The M cars are in a different league to the car you and me both had. I don't bother with the radio or CD anymore the sound of the M cars is amazing and you will enojy every bit of that 338 BHP
