If you can live with the warning light, and can remember to check your tire pressures at least every other week, then you don't have to do that. You could wait until the next replace-the-tires cycle and get TPMS units from; e.g., tirerack.com.I just purchased new wheels and tires, and they were mounted for me at the shop, then shipped to me. Am I going to have the tire shop dismount the new tire and old tire, take out the TPS, and remount? If this is the case, it's going to be expensive
WORD--Actually my Enkei NT03's have 2 valve stems: So that you can check the tire pressure on one as you add air with the other! Also glad that the Cdn Car comes fully equipped w/ Prem. Package. Don't really care about the fact that Navi isn't available: I'd rather buy my own system if I want to at a 1/4 of the cost. I do wish that we got the 10 speaker stereo instead of the standard 6-spkr setup. Oh well.Hurray for the canadian WRX which dont come with this silly option !!
