On an '06 with the NAV option or the Chrono Pack, the clock is in the speedometer on the steering column - you briefly press the trip odometer button to toggle between displaying the trip odometer and the clock.

On a non-NAV / non-Chrono '06, I think the clock is in the center speedometer.

Looks like you already have all the key areas of the car covered. Deffinately swap the run flats out with the other rims and tires. There are loads of ways to make your car the way you want it, and a lot of aftermarket support to get the right parts. Do some research, look through the websites and forums, find a local club, and go out to some meetings, maby even one of the national events. Just enjoy the car, and add to it as you find stuff that you dont like about the car.

 

My plan for my "new to me" R53 is going to be a Milltek catback exhaust to get rid of the one ball mod exhaust. I don't know why it bothers me but it just feels kinda cheap and unprofessional.
