Congrats Gnil!

Great that you could get the tire pressure monitoring system, you will be so gald you were able to, and I'm not sure retrofit is porsible.

I would definately not get the spacers. You are getting the -20mm! and other sport extras, and with the spacers you are changing that car's track. That will not have a positive inpact on the car's handling, its pure phisics, there is no point IMO. If you are going -20mm you might as well avoid spacers and such stuff. But thats personal.

Also Park assist is less noticiable in the 997 than in the 996, but still obvious and doesn't look very sporty. So unless you have problems parking, I would not get it.

I's a wonderfully spec'd car and you will love it... now the wait!
