Is it possible to have TPMS integrated into a 03.5 sedan? I was at the stealership the other night and the guy looked at me like a had three heads. He said the 03 rims didnt have TPMS so the car isnt equipped for it therefore I cant do it. For some reason I just doubt that its impossible. I have G37 rims w/ TPMS if it makes any difference. If anyone can clear it up for me, it would be appreciated.
